Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

Paraphrasing the term:
loading: external forces and other factors applied to an engineered structure to cause internal forces or deformations of the engineered structure or component may include various forces applied directly to the structure, as well as other effects on the structure that cause additional deformations and constrain deformation.
Consolidation: refers to the process of converting loose sediment into consolidated rock, also known as consolidation.
Degree of consolidation: the method is a parameter for representing the consolidation degree of a soil layer or a soil sample, and particularly refers to the ratio of the average dissipation value or the compression amount of the pore water pressure to the increment of the initial pore water pressure or the final compression amount of the pore water pressure at a certain moment in the consolidation process of the soil layer or the soil sample under a certain level of load, which is usually expressed in the form of percentage.

Soft soil: the clay soil is a general name of clay soil with large water content and pore ratio, low shearing strength and permeability, high compressibility and high sensitivity, and comprises silt, mucky soil, sub-clay, sub-sandy soil and the like.
And (3) settling: under the action of load, the foundation soil layer is vertically deformed or sunk due to compression. The uneven settlement has great harm to the building, can cause the building to generate additional stress to cause cracks, even causes local construction fracture, and endangers the safety of the building.
Fig. 1 is a schematic flow chart of a second embodiment of the method for obtaining average consolidation degree according to the present invention. The execution subject of the average consolidation degree obtaining method provided by the embodiment of the present invention may be the average consolidation degree calculating device or the electronic device provided by the embodiment of the present invention, for example, the electronic device may be a smart phone, a computer, or the like. In this embodiment, an execution subject is taken as an example of a computer.
As shown in fig. 1, the method of this embodiment may include:
s101, reinforcing the foundation by adopting a one-stage or multi-stage constant-speed loading mode, and obtaining loading duration and total load.
Because the stability of the soft soil foundation of the building is poor, the settlement is large under the action of external load, and the bearing capacity and the stability of the soft soil foundation can not meet the engineering requirements, the foundation needs to be reinforced to reduce the settlement or uneven settlement of the upper structure of the building.
The concrete implementation modes of the reinforcement treatment are various, for example: in the embodiment, a one-stage or multi-stage constant-speed loading mode is adopted to perform pre-pressing and reinforcing treatment on the foundation, and after the reinforcing treatment is completed, corresponding loading duration and total load are obtained. Specifically, if a primary constant-speed loading mode is adopted to reinforce the foundation, a first loading duration and a total load corresponding to the primary loading are obtained; and if the foundation is reinforced by adopting a multistage constant-speed loading mode, acquiring second loading duration and total load corresponding to each stage of constant-speed loading.
One possible implementation: the computer displays an input interface on a display unit of the computer, and a user inputs the loading duration and the total load into the computer through the input interface.
Another possible implementation: the reinforcement processing related data is stored in a storage medium in the form of a data template, a computer is connected with the storage medium, and the computer automatically acquires data information corresponding to the keyword in the data template according to the keyword.
Of course, the loading duration and the total load may be input to the computer in other ways, such as voice input.
And S102, obtaining the average consolidation degree of the foundation according to an average consolidation degree calculation formula.
In this step, the loading duration t 0 The total load sigma delta P and the load rate q are substituted into the average consolidation degree calculation formula, so that the average consolidation degree of the foundation can be obtained
Wherein, the average consolidation degree calculation formula is as follows:
in the calculation formula of the average consolidation degree,
represents the average consolidation degree of the foundation, q represents the loading rate of the load, sigma delta P represents the total load, t 0 Representing the total loading time, U (t) is a function of consolidation degree, U (t) = 1-alpha e βt α denotes a first coefficient, and β denotes a second coefficient.
Note that α and β are both known constant coefficients. In particular, the amount of the solvent to be used,
in practical application, two digits after the decimal point are taken, so that the value of alpha is usually 0.81.
Wherein d is e Represents the effective diameter of the shaft in units of: rice (M); c h Represents the radial drainage consolidation coefficient of soil, and the unit is: square meter per day (M) 2 /d)；C v The vertical drainage consolidation coefficient of the soil is expressed by the unit: square meter per day (M) 2 D); h represents the vertical drainage distance of the soil layer, and the unit is as follows: rice (M); f is a composite parameter, which consists of three parts, which can be expressed as: f = F n +F s +F r Dimensionless, wherein F n Reflecting the influence of the well diameter ratio n, F s Reflecting the effect of smearing perturbation, F r Reflecting the well resistance effect, the specific calculation method is similar to that in the prior art and is not described here.
It should be noted that for the shaft foundation, β is a parameter value without considering the smearing and well resistance effects.
In practical application, if the foundation is reinforced by adopting a one-stage constant-speed loading mode, parameters such as a first loading time length, a total load, a loading rate of a load and the like corresponding to the one-stage constant-speed loading time length can be directly substituted into an average consolidation degree settlement formula to obtain the average consolidation degree of the foundation.
If the foundation is reinforced by adopting a multi-stage constant-speed loading mode, the average consolidation degree corresponding to each stage of constant-speed loading can be calculated according to the second loading duration and the total load corresponding to each stage of constant-speed loading, and the sum of the average consolidation degrees corresponding to each stage of constant-speed loading is used as the average consolidation degree of the foundation, that is, when the foundation is reinforced by adopting a multi-stage (m stages, m is an integer greater than or equal to 2) constant-speed loading mode, the average consolidation degree calculation formula is as follows:
wherein q is i The loading rate of the load when the ith level is loaded at the constant speed is represented; t is t i-1 The loading starting time is shown when the i-th level constant speed loading is carried out; t is t i Indicating the loading end time when the i-th level is loaded at the same speed; wherein i is an integer less than or equal to m.
In this embodiment, the foundation is reinforced by one-stage or multi-stage constant-speed loading to obtain the loading duration and the total load, and further, the average consolidation degree of the foundation is obtained according to an average consolidation degree calculation formula, and the average consolidation degree is used for representing the stability of the foundation. By adopting the average consolidation degree calculation formula provided by the embodiment, the average consolidation degree of the foundation can be quickly obtained, so that a basis is provided for stability evaluation of the foundation. Because the calculation formula of the average consolidation degree provided by the embodiment is simpler, the calculation amount can be reduced, and the calculation efficiency is effectively improved.
In order to make the technical solution of the embodiment of the present invention clearer, how the above calculation formula of the average consolidation degree is obtained is described in detail here. Fig. 2 is a first schematic diagram illustrating a relationship between a load and a loading duration.
Assuming that a building foundation is reinforced in the manner shown in FIG. 2, it can be seen from FIG. 2 that the foundation is Δ P 3 Consolidation at delta t under load 3 The time of (d); foundation at delta P 2 Under the action of load solidify delta t 2 +Δt 3 The time of (d); foundation at delta P 1 Under the action of load solidify delta t 1 +Δt 2 +Δt 3 The time of (d); and Δ P 3 、ΔP 2 、ΔP 1 The corresponding final sedimentation is proportional to Δ P 3 、ΔP 2 、ΔP 1 The magnitude of the load.
Assuming the consolidation function is U (t), then the following equation exists:
in particular, when Δ t 3 ＝Δt 2 ＝Δt 1 ＝Δt→0，ΔP 3 ＝ΔP 2 ＝ΔP 1 = Δ P → 0, the consolidation degree, which can be regarded as the constant velocity loading, is calculated, and Δ t = dt is taken and the above equation is differentiated to obtain:
further, the following can be obtained:
wherein, P Starting point Indicating the magnitude of the load at the initial moment of loading, usually P Starting point =0, unit is: kilopascals (kPa);
P final (a Chinese character of 'gan') Indicating the magnitude of the load at the end of the loading, i.e. the magnitude of the total load, and therefore P Final (a Chinese character of 'gan') =ΣΔ P, unit: kilopascals (kPa); Δ P represents the increment of the load at each stage of isokinetic loading relative to the previous stage of isokinetic loading.
t Starting point Indicating the moment at which loading is to begin, typically t Starting point =0, unit is: day (d);
t terminal Indicating the moment at which the load is finished, i.e. the duration of the load, and therefore, typically t Final (a Chinese character of 'gan') ＝t 0 The unit is: day (d);
order to
It represents the loading rate of the load in units of: kPa/d.
The above formula is further simplified, and the obtained average consolidation degree calculation formula is as follows:
wherein α and β are both known constant coefficients, and refer to the description in the embodiment shown in fig. 1, which is not described herein again.

And S303, determining the stability evaluation result of the foundation according to the average consolidation degree of the foundation and the preset judgment condition.
One possible implementation manner is to numerically convert the preset determination result into a specific preset threshold, and determine whether the stability of the foundation meets the requirement by comparing the average consolidation degree of the foundation with the preset threshold. For example: if the average consolidation degree is greater than or equal to a preset threshold value, determining that the foundation meets the stability requirement, namely determining that the stability evaluation result meets the stability requirement; and if the average consolidation degree is smaller than the preset threshold value, determining that the foundation does not meet the stability requirement, namely, the stability evaluation result is that the stability requirement is not met.
Preferably, the preset threshold is 80%. Of course, the preset threshold may also be set to other values, which is not limited in this embodiment of the present invention. It will be appreciated that the higher the preset threshold, the higher the stability requirement of the foundation accordingly.
And S304, displaying the stability evaluation result.
And displaying the stability evaluation result on a display unit of the computer so that a user can intuitively know the stability condition of the current foundation through a visual interface and provide a basis for the next decision. For example: if the average consolidation degree of the foundation is greater than a preset threshold value, displaying that the stability requirement is met on a display unit of the computer; if the average consolidation degree of the foundation is less than the preset threshold value, displaying that the stability requirement is not met on a display unit of the computer, so that a user can know that the building foundation needs to be further reinforced until the stability requirement is met.
Furthermore, the average consolidation degree of the foundation can be displayed on a display unit of the computer, so that a user can obtain the stability evaluation result of the current foundation and can know the difference between the average consolidation degree of the current foundation and the preset judgment standard, and further a decision basis is provided for the next consolidation treatment.
In this embodiment, a one-stage or multi-stage constant-speed loading manner is adopted to reinforce the foundation, so as to obtain the loading duration and the total load, then the average consolidation degree of the foundation is obtained according to an average consolidation degree calculation formula, and the average consolidation degree is used to represent the stability of the foundation, and further, according to the average consolidation degree of the foundation and a preset determination condition, the stability evaluation result of the foundation is determined, and the stability evaluation result is displayed.

By adopting the method, the total loading time t 0 =120 days, total load Σ Δ P =100kPa, for the first stage isokinetic loading period, q =6, for the second stage isokinetic loading period, q =4, and, in addition, α =0.81, β =0.251. Further, substituting the parameters into an average consolidation degree calculation formula, and simplifying to obtain:
