Detailed Description
The invention will be further described with reference to the drawings and examples.
Example 1
In one or more embodiments, as shown in fig. 1, a power distribution room design method is provided, which includes the following steps:
s1, establishing a three-dimensional geological model, an initial power distribution room foundation model and an initial power distribution room overall model, and performing sedimentation simulation on the initial power distribution room foundation model and the initial power distribution room overall model;
s2, designing a power distribution room simulation basic model according to the settlement simulation result, and performing settlement simulation on the power distribution room simulation basic model to obtain a first settlement result;

s7, installing a power distribution room foundation, and pre-correcting inclination of the power distribution room foundation;
and S8, installing a prefabricated wall body and a prefabricated roof on the basis of the power distribution room after pre-correcting the inclination.
The settlement of a building under long-term load generally comprises initial settlement, also called instantaneous settlement, which is the settlement occurring at the moment of load application, and consolidation settlement, which comprises primary consolidation settlement and secondary consolidation settlement, which is the settlement occurring in the process of continuously removing pore water in foundation soil after load application. Because consolidation sedimentation is sedimentation which occurs with time after load is applied, the prior art can only correct the initial sedimentation without considering the consolidation sedimentation, and therefore, the embodiment provides a brand new design method aiming at correction and compensation of the consolidation sedimentation.
In step S1, a three-dimensional geological model of a formation on a construction site needs to be acquired first, and the three-dimensional geological model can be built based on site drilling data and engineering geological profile information, or can be built through rayleigh wave detection and other modes.
The initial power distribution room basic model and the initial power distribution room overall model can be designed according to the existing design specifications, and the model established in the past can be directly used, and the model is required to be adjusted according to the simulation result in the follow-up process, so that the design is carried out according to a conventional design method.
And the settlement simulation simulates the settlement condition by using a finite element analysis mode, inputs finite element calculation parameters according to a three-dimensional geological model, respectively carries out settlement simulation on an initial power distribution room base model and an initial power distribution room integral model, and judges whether settlement amount and settlement deviation meet design requirements. The design requirements can refer to the allowable settlement and inclination of the building in national standards, and can also be specifically required according to the design specifications of the actual power distribution room.
In step S2, designing a power distribution room simulation basic model according to the sedimentation simulation result, including:
s21, if the settlement of the initial power distribution room integral model does not meet the requirement, reinforcing a power distribution room foundation or replacing the installation position of the power distribution room;
s22, if the settlement amount of the initial power distribution room integral model meets the requirements, and the settlement deviation of the initial power distribution room base model and the settlement deviation of the initial power distribution room integral model do not meet the requirements, redesigning the initial power distribution room base model and the initial power distribution room integral model according to the simulation result, or reinforcing a power distribution room foundation, and then re-simulating;
s23, if the settlement amount of the initial power distribution room integral model meets the requirements, the settlement offset of the initial power distribution room basic model does not meet the requirements, but the settlement offset of the initial power distribution room integral model meets the requirements, and the initial power distribution room basic model is the power distribution room simulation basic model at the moment;
s24, if the settlement amount of the initial power distribution room integral model meets the requirements, the settlement offset of the initial power distribution room basic model meets the requirements, but the settlement offset of the initial power distribution room integral model does not meet the requirements, modifying the initial power distribution room integral model, adjusting load distribution, and re-simulating; if the whole model of the initial power distribution room still does not meet the sedimentation deviation requirement after modification, reinforcing a power distribution room foundation or increasing the contact area between the basic model of the initial power distribution room and the ground;
s25, if the settlement amount of the initial power distribution room overall model meets the requirements, and the settlement offset of the initial power distribution room basic model and the settlement offset of the initial power distribution room overall model meet the requirements, the initial power distribution room basic model is the power distribution room simulation basic model. The settlement amount is the settlement amount of the whole building, corresponds to the settlement amount in the standard, and the settlement offset is the whole inclination condition of the building, corresponds to the inclination amount in the standard.
In step S21, since the initial power distribution room overall model includes the initial power distribution room foundation, the initial power distribution room prefabricated wall, the initial power distribution room prefabricated roof and the initial power distribution room equipment, that is, the initial power distribution room overall model itself includes the initial power distribution room foundation model, if the settlement of the initial power distribution room overall model does not meet the requirement, the settlement of the initial power distribution room foundation model does not meet the requirement, so that the settlement is judged by only analyzing the initial power distribution room overall model. When the settlement of the integral model of the initial power distribution room does not meet the requirement, the soil structure under the topography of the place is loose, or the pore water in the soil is more, so that the settlement is larger. The bearing capacity of the foundation can be increased by the methods of reinforcing the foundation, thickening the foundation and the like, so that sedimentation is reduced, or the installation position of the power distribution room is selected again.
If the settlement of the whole model of the initial power distribution room meets the requirement, entering a subsequent step, and judging the settlement offset.
In step S22, if the sedimentation deviation of the initial power distribution room basic model and the initial power distribution room overall model is not satisfactory, it may be caused by the uneven distribution of the underground soil or the current model may be problematic. Judging whether the load is mainly caused by uneven distribution of underground soil according to the three-dimensional geological model, if so, reinforcing the power distribution room foundation simultaneously to reduce settlement offset, or redesigning an initial power distribution room foundation model and an initial power distribution room integral model, mainly redistributing the load so that the load is mainly loaded on one side with smaller settlement amount, and then, carrying out simulation again to observe whether the design requirement can be met; if the settlement deviation is mainly caused by the model problem, the initial power distribution room base model and the initial power distribution room overall model are redesigned according to the simulation result, and then the simulation is carried out again. When the initial power distribution room foundation model and the initial power distribution room overall model are redesigned, the settlement deviation requirement of the initial power distribution room overall model is mainly considered to be met, the layout position of initial power distribution room equipment in the model can be adjusted at first to adjust load distribution, if the design requirement still cannot be met after adjustment, the initial power distribution room foundation model can be adjusted, the quality distribution of the initial power distribution room foundation model is adjusted, or the contact area between the power distribution room foundation model and the ground is increased.
In step S23, if the settlement offset of the initial power distribution room basic model does not meet the requirement, but the settlement offset of the initial power distribution room overall model meets the requirement, the initial power distribution room basic model is the power distribution room simulation basic model at this time as long as the settlement offset of the initial power distribution room overall model can be ensured to meet the requirement because the initial power distribution room overall model corresponds to the finally installed power distribution room.
In step S24, if the settlement offset of the basic model of the initial power distribution room meets the requirement, but the settlement offset of the overall model of the initial power distribution room does not meet the requirement, it indicates that after the loads of the prefabricated wall body of the initial power distribution room, the prefabricated roof of the initial power distribution room and the initial power distribution room equipment are increased, additional settlement offset is caused, at this time, the overall model of the initial power distribution room needs to be modified, the load distribution (the position of the initial power distribution room equipment is preferentially adjusted), and the simulation is performed again; and if the whole model of the initial power distribution room still does not meet the sedimentation deviation requirement after modification, reinforcing the foundation of the power distribution room, or increasing the contact area between the foundation model of the initial power distribution room and the ground.
In step S25, if the settlement amount and the settlement offset can meet the requirements, it is indicated that the initial power distribution room base model and the initial power distribution room overall model established at this time are reasonable, and the initial power distribution room base model is used as a power distribution room simulation base model.
In step S2, a first sedimentation result is obtained through simulation, where the first sedimentation result includes a first sedimentation amount and a first offset amount, and is used for subsequent error calculation, so as to adjust the three-dimensional geological model according to the actual situation, and improve the simulation accuracy.
In step S3, according to the power distribution room simulation basic model obtained in step S23 or S25, manufacturing and installing a power distribution room simulation basic, observing the sedimentation occurring after the installation of the power distribution room simulation basic, and obtaining a second sedimentation result, where the second sedimentation result includes a second sedimentation amount and a second offset, and the second sedimentation result can directly measure the sedimentation after the installation of the power distribution room simulation basic, i.e. initial sedimentation, or can be kept stand for a period of time after the installation of the power distribution room simulation basic, and measure the consolidation sedimentation occurring in the period of time so as to improve the subsequent simulation precision, specifically how to select, and can be selected according to actual conditions (such as requirements of construction period).
In step S4, an error between the first sedimentation result and the second sedimentation result is calculated, and the calculation method is as follows:
wherein a is an error,for the first settlement amount, ++>For the second settlement amount->For the first offset, +>And m is a sedimentation weight coefficient, and n is an offset weight coefficient.
The error a is a schematic value, which does not have an actual physical meaning, but can be merely used as a schematic of an error between the first sedimentation result and the second sedimentation result. Because the observation time is limited, the first sedimentation result and the second sedimentation result are both dominated by initial sedimentation, namely the absolute value of the sedimentation quantity is larger than or far larger than the absolute value of the offset quantity, so that in order to balance the relation between the first sedimentation result and the second sedimentation result, a weight coefficient is required to be introduced for compensation, and the size of the offset weight coefficient n is larger than the sedimentation weight coefficient m so as to improve the influence of the offset quantity on the error a.
And after the error a is obtained, adjusting the three-dimensional geological model according to the error a. Presetting an error setting threshold value x, adjusting parameters of a three-dimensional geological model according to the error a, re-simulating sedimentation of a simulation basic model of the power distribution room by using the adjusted model, and calculating the re-simulated error; and (3) through iterative adjustment until the error a is smaller than the error setting threshold value x, at the moment, the parameters of the three-dimensional geological model are considered to be matched with the actual address characteristics of the construction site, and the adjusted three-dimensional geological model is obtained and is used for subsequent simulation design.
In step S5, the adjusted three-dimensional geological model is used for designing a final power distribution room basic model and a final power distribution room overall model. Because the three-dimensional geological model is adjusted, the result of subsidence simulation can be influenced, and the adjusted three-dimensional geological model is needed to be used for carrying out subsidence simulation on the power distribution room simulation basic model and the initial power distribution room overall model which are established before. And if the simulation result still meets the requirement, taking the power distribution room simulation basic model as a final power distribution room basic model, and taking the initial power distribution room overall model as a final power distribution room overall model. If the simulation result of the initial power distribution room overall model does not meet the requirement, the initial power distribution room overall model needs to be adjusted, and the adjusted model is used as a final power distribution room overall model.
In step S7, after the power distribution room foundation is installed, pre-correcting the power distribution room foundation according to the sedimentation simulation result of the final power distribution room overall model in step S5. The shallow soil excavation inclination correction method can be used for correcting inclination, and small-amplitude shallow soil excavation is carried out on a position with small settlement in settlement simulation, so that settlement amount at the position is properly increased, inclination degree after a power distribution room is installed is reduced, and solidification settlement is compensated during installation. Because the overall installation back height of electricity distribution room is lower, and the fixed setting of internal equipment is subaerial, and the focus is lower, can allow to exist the slope of a small margin when being under construction. When pre-rectifying, the pre-rectifying amplitude needs to be controlled, and because the prefabricated wall body of the power distribution room, the prefabricated roof of the power distribution room and the power distribution room equipment are not installed at the moment, the consolidation settlement at the moment can be compensated only when the settlement simulation of the final power distribution room foundation model and the final power distribution room overall model incline towards the same direction in general, and the inclination amount of the power distribution room foundation after pre-rectifying needs to meet the requirements of national standards or design standards.
The final power distribution room integral model is designed according to the adjusted three-dimensional geological model, so that the final power distribution room integral model is designed after the design construction requirement and the requirement on the inclination amount in the standard are comprehensively considered, and a certain deviation amount can be designed within the inclination degree allowed by the standard in order to meet the actual construction and use requirements.
And setting a simulated deviation setting threshold according to actual conditions, if the deviation amount of the final overall power distribution room model is smaller than the simulated deviation setting threshold, pre-correcting the inclination by directly using a shallow soil excavation inclination correction method, and setting the deviation amount by back inclination of a power distribution room foundation according to the deviation amount of the final overall power distribution room model. The amplitude of the camber may typically be one-fourth to one-third of the amount of offset of the simulation, and should not exceed one-half. If the deviation (the height difference between the highest point and the lowest point of the foundation of the power distribution room) of the final overall model of the power distribution room obtained through simulation is 5cm, the foundation of the power distribution room can be tilted back by about 1.5cm during construction, on one hand, the tilting degree is within the standard requirement range, the influence on the overall structural strength of the power distribution room is small, and on the other hand, the follow-up consolidation settlement can be compensated to a certain degree; and after tilting back, the load changes, so that the load acts more on the position where the original settlement is smaller (namely the geological structure is tighter), the settlement condition of consolidation settlement can be slightly changed, and the subsequent offset is reduced.
If the offset of the final overall power distribution room model is larger than the simulated offset setting threshold, pre-correcting inclination can be carried out by using a shallow soil excavation inclination correction method, and the foundation inclination of the power distribution room is set to be offset according to the settlement of the final overall power distribution room model; in addition, the simulated inclined direction power distribution room foundation needs to be reinforced in an anti-tilting mode. Because the inclination correction effect is limited in a mode of correcting the inclination in advance through the inclination correction, when the designed offset is larger than the analog offset set threshold value, other measures are needed to be additionally taken to perform inclination prevention reinforcement on the power distribution room foundation, the strength of the power distribution room foundation can be improved through the inclination prevention reinforcement on one hand, the future foreseeable inclination is supported, and on the other hand, the possible inclination can be reduced to a certain extent.
The anti-tilting reinforcement mode can be adopted to increase the foundation area, increase the supporting pile body, strengthen the foundation and the like. For the increase basic area, can extend the distribution room basis in earth's surface or underground position, increase the area of contact of one side and ground of distribution room basis incline direction, on the one hand can even load, on the other hand the part that extends can provide certain effort when taking place the slope to reduce the inclination of distribution room itself. To increasing the support pile body, can additionally set up many support piles in the bottom of distribution room foundation incline direction, carry out the additional support to the distribution room of slope one side through the support pile. To consolidate the ground, can cooperate to increase to support pile body synchronous implementation, consolidate the processing through the ground to the distribution room foundation below of slope one side, increase this partial intensity of ground to reduce subsidence, cooperation support pile supports the distribution room foundation behind the increase foundation intensity, in order to further avoid the slope of distribution room.
In step S8, after installing the prefabricated wall body and the prefabricated roof, the method further includes: observing the power distribution room, and if the power distribution room does not incline within a set time, installing power distribution room equipment according to a final power distribution room overall model; if the power distribution room is inclined within the set time and the offset does not exceed the offset set threshold, determining the installation position of the power distribution room equipment according to the offset when the power distribution room equipment is installed.
Because the pre-rectification is performed in step S7, the power distribution room after the installation of the prefabricated wall body and the prefabricated roof needs to be observed for a certain time. If the power distribution room does not incline obviously within the set time (for example, 7 days), the power distribution room equipment can be directly installed according to the whole power distribution room model; if the power distribution room is inclined in a set time, but the offset does not exceed the offset set threshold, the installation position of the power distribution room equipment can be determined according to the offset when the power distribution room equipment is installed, and the position of the power distribution room equipment is properly adjusted, so that the power distribution room equipment is slightly close to a place with small settlement (namely, a higher position in the power distribution room after the inclination occurs), and the inclination degree of the power distribution room is reduced through the redistribution of loads. If the offset exceeds the set threshold, the offset indicates that the deviation exists in the early simulation process or the pre-rectification process, and the construction needs to be performed again, and at the moment, the prefabricated wall body and the prefabricated roof can be rapidly disassembled and rectification is performed again because the power distribution room equipment is not installed yet.
According to the embodiment, the error between the settlement simulation result (first settlement amount) and the actual settlement observation result (second settlement amount) of the power distribution room simulation foundation is obtained by designing the power distribution room simulation foundation, so that the established three-dimensional geological model is corrected, and the model simulation accuracy is improved; and (3) designing a final power distribution room basic model and a final power distribution room overall model by using the corrected model, and pre-correcting inclination according to a simulation result after the power distribution room foundation is installed, so that inclination correction compensation for consolidation settlement is realized.
