JP6871502B2 - Pile foundation design system, design method and design program - Google Patents

Description

The present disclosure relates to a pile foundation design system, a design method and a design program.

Patent Document 1 discloses a pile foundation design support system. The pile foundation design support system can design pile foundations based on geological data and N value (penetration test data). The pile foundation design support system can use the geological data and N value input by the user of the system, but can also use the geological data and N value registered in the geological database.

Japanese Unexamined Patent Publication No. 2002-351941

As disclosed in Patent Document 1, geological data and N value are indispensable for the design of pile foundations and have a great influence on the design of pile foundations. Therefore, it is desirable that the geological data (soil classification) and N value used for the design of pile foundations are as accurate as possible.
However, the geotechnical investigation for obtaining geological data and N value is not completely automated, and there is a problem that the accuracy of geological data and N value tends to be low. For example, in terms of soil quality classification, there are silt mixed with sand, silt fine sand, etc., but it is not easy to always accurately determine the soil quality. On the other hand, when measuring the N value, it is necessary to repeatedly pull up the weight to a certain height, but the height of pulling up may vary. Further, in the first place, due to the properties of the ground, for example, the non-landing of the support layer, the geological data and the N value are likely to vary, and the accuracy is likely to be low.

In view of the above circumstances, an object of at least one embodiment of the present invention is to provide a pile foundation design system, a design method and a design program capable of designing a pile foundation based on more accurate ground information.

Hereinafter, some embodiments of the present invention will be described with reference to the accompanying drawings. However, the dimensions, materials, shapes, relative arrangements, etc. of the components described as embodiments or shown in the drawings are not intended to limit the scope of the present invention to this, but are merely explanatory examples. Absent.

FIG. 1 is a block diagram showing a schematic configuration of a pile foundation design system (hereinafter, also simply referred to as a design system) according to an embodiment of the present invention.
The design system includes a pile foundation design ground survey result preparation unit 10, a recording unit 12, a comparative ground survey result preparation unit 14, a ground survey result determination unit 16, and a pile foundation design unit 18. The ground investigation result preparation unit 10 for pile foundation design, the ground investigation result preparation unit 14 for comparison, the ground investigation result determination unit 16 and the pile foundation design unit 18 are, for example, a CPU (central processing unit), an internal memory, and an input / output unit. It is composed of a computer (electronic computer) having the above. The recording unit 12 is composed of, for example, an external storage device such as a hard disk.

The pile foundation design ground survey result preparation unit 10 is configured to prepare the ground survey results (pile foundation design ground survey results) at the construction site of the pile foundation to be constructed. For example, the pile foundation design ground survey result preparation unit 10 is configured to receive the pile foundation design ground survey results sent by e-mail or the like. Further, for example, the pile foundation design ground survey result preparation unit 10 may be configured so that the pile foundation design ground survey result is directly input by the operator.

The recording unit 12 stores the database 20. The database 20 includes a plurality of location information and information on the ground survey results associated with each of the plurality of location information.
The location information may be an address, or may be latitude and longitude.
The results of the geotechnical investigation are obtained by, for example, a boring survey, and at least the geological data showing the distribution of the geology (soil classification) in the depth direction and the distribution of the N value obtained in the standard penetration test in the depth direction. It suffices to include N value data representing. The ground survey results may further include the depth of the support layer and the groundwater level.

The comparative ground survey result preparation unit 14 is configured to search the database 20 and prepare the ground survey results associated with the location information of the construction site or the vicinity of the construction site as the comparative ground survey results.

The ground investigation result determination unit 16 compares the pile foundation design ground investigation result prepared by the pile foundation design ground investigation result preparation unit 10 with the comparison ground investigation result prepared by the comparison ground investigation result preparation unit 14. , It is configured to judge the accuracy of the ground survey results for pile foundation design.
As the determination result, for example, it may be determined that the accuracy of both the geological data and the N value data included in the pile foundation design ground investigation result is high from the comparison with the comparative ground investigation result.
Further, for example, it may be determined that the accuracy of the geological data and the N value included in the pile foundation design ground survey result is low from the comparison with the comparative ground survey result.

The pile foundation design unit 18 is configured to design the pile foundation based on the determination result by the ground survey result determination unit 16.
For example, when it is determined that the accuracy of the ground survey result for pile foundation design is high, the pile foundation design unit 18 designs the pile foundation by using the ground survey result for pile foundation design as it is. Designing a pile foundation means determining the overall configuration of the pile foundation so that the pile foundation has a predetermined allowable bearing capacity according to the superstructure supported by the pile foundation, for example, the specifications of the pile to be used. , The number of piles, the number of pile holes, the depth of pile holes, the position of pile holes, etc.
On the other hand, when it is determined that the accuracy of the ground survey result for pile foundation design is low, the pile foundation design unit 18 does not use the ground survey result for pile foundation design as it is, but designs the pile foundation in anticipation of safety. To do. For example, when it is determined that the N value data of the ground survey result for pile foundation design is high, the pile foundation design unit 18 underestimates the N value data and designs the pile foundation. Further, for example, when it is determined that the accuracy of the ground survey result for pile foundation design is low, the ground survey result for pile foundation design may be corrected so that the accuracy is high. Then, the correction coefficient used for the correction and the value of the ground survey result for the pile foundation design after the correction may be registered in the database 20 in association with the position information.
Alternatively, if it is determined that the accuracy of the ground survey result for pile foundation design is low, the pile foundation design unit 18 may be configured to request an additional ground survey result. For example, a construction site where it is presumed that uneven land has occurred by designating the points between the points where the ground survey for pile foundation design was conducted and requesting the survey again, or by referring to the results of the comparative ground survey. It may be configured to request a specific location for the investigation.

According to the above embodiment, the accuracy of the ground survey result for pile foundation design is determined by comparing the ground survey result for pile foundation design with the ground survey result for comparison, so that it is for more accurate pile foundation design. Pile foundations can be designed based on the results of ground surveys.

In some embodiments, the database 20 further includes measurement result information of an index corresponding to the resistance acting on the excavation drill from the ground during the excavation of the pile hole, which is associated with each of the plurality of position information. .. Then, the ground survey result determination unit 16 is configured to consider the measurement result of the index.
As indicators, for example, the current value supplied to the electric motor when the motor for rotating the drilling drill is an electric motor, the time integration value of the current value, and the hydraulic pressure supplied to the hydraulic motor when the motor is a hydraulic motor. A time-integrated value of a value and a hydraulic value, a torque value acting on a drill, a time-integrated value of a torque value, and the like can be used. The measurement result of the index represents the distribution of the measurement result of the index in the depth direction.

As an example of considering the information of the measurement result of the index, it is possible to use the measurement result of the index in order to extract a highly reliable comparative ground survey result from a plurality of comparative ground survey results. There is a possibility that some of the results of the comparative ground survey have low accuracy and low reliability of soil classification and N value data. When comparing the results of the unreliable comparative ground survey with the results of the foundation design ground survey, even if the accuracy of the foundation design ground survey results is actually high, there is a risk that the accuracy will be erroneously determined to be low. There is.
Therefore, it is important to extract highly reliable results from the comparative ground survey results and compare the highly reliable comparative ground survey results with the foundation design ground survey results. The question is whether to confirm the reliability of the ground survey results.
Here, the measurement result of the index has a certain degree of correlation with the soil classification and N value data, and in some cases, has a high correlation. Therefore, if the comparative ground survey results that are highly correlated with the index measurement results are extracted, it is possible to extract highly reliable comparative ground survey results with high accuracy of soil classification and N value data.
Thus, if only the comparative ground survey results that are highly correlated with the measurement results of the indicators corresponding to the positions are extracted and the extracted comparative ground survey results are compared with the foundation design ground survey results, a highly reliable comparison is made. It is possible to compare the results of the ground survey for the foundation design with the results of the ground survey for the foundation design, and the accuracy of the results of the ground survey for the foundation design can be accurately determined.
Further, as an example of considering the information of the measurement result of the index, the measurement result of the index and the ground survey result for the pile foundation design may be directly compared to determine the accuracy. The measurement result of the index has a certain degree of correlation with the soil classification and N value data, and in some cases, has a high correlation. Therefore, it is possible to judge the accuracy of the pile foundation design ground survey result by comparing the index measurement result with the pile foundation design ground survey result.
On the other hand, at the construction site of pile foundations, the number of pile holes is larger than the number of survey points in the ground survey, and there are a large number of index measurement results. Although the measurement results of each index do not specifically represent the soil classification and N-value data as much as the comparative ground survey results, the soil classification and N-value data can be made accurate to some extent by using the measurement results of a large number of indicators. Can be estimated to.
Therefore, it is possible to judge the accuracy of the pile foundation design ground survey result by directly comparing the index measurement result and the pile foundation design ground survey result.

Thus, according to the above embodiment, since the accuracy of the ground survey result for the pile foundation design is determined in consideration of the information of the measurement result of the index, the accuracy of the ground survey result for the pile foundation design is determined more accurately. be able to. As a result, according to the above embodiment, the pile foundation can be designed based on the more accurate ground survey result for the pile foundation design.

In some embodiments, the design system further comprises an index measurement result weighting unit 22 that weights the index measurement results according to the conditions of pile hole excavation. The index measurement result weighting unit 22 can be configured by, for example, a computer. Then, the ground survey result determination unit 16 is configured to consider the weight information attached to the measurement result of the index.

The measurement result of the index changes depending on the conditions of pile hole excavation. Therefore, at present, the measurement results of all indicators are not comparable to the ground survey results. Therefore, a large weight is given to the measurement result of the index measured when the pile hole is excavated under the predetermined pile hole excavation condition comparable to the ground survey result, and the measurement result of the index with a large weight is given. By comparing with the comparative ground survey results, more reliable comparative ground survey results can be extracted. Alternatively, the measurement result of the index with a larger weight may be directly compared with the ground survey result for pile foundation design.

Thus, according to the above embodiment, the accuracy of the ground survey result for pile foundation design is determined in consideration of the weight information attached to the measurement result of the index. Therefore, the accuracy of the ground survey result for pile foundation design is determined. It can be judged more accurately. As a result, according to the above embodiment, the pile foundation can be designed based on the more accurate ground survey result for the pile foundation design.
The weight attached to the measurement result of the index may change stepwise or continuously, and may be, for example, only 0 and 1.

In some embodiments, the database 20 further includes measurement result information of an index corresponding to the resistance acting on the excavation drill from the ground during the excavation of the pile hole, which is associated with each of the plurality of position information. Then, the design system further includes a ground survey result weighting unit 24 that weights the ground survey result based on the degree of correlation between the position information and the measurement result of the corresponding index.
