[0001] This invention relates to the technical field of pile foundation testing, and in particular to a loading method and system for static load testing of pile foundation compressive strength. Background Technology

[0002] With the advancement of urbanization, the construction industry is developing at an increasingly rapid pace, and buildings are becoming increasingly taller, which places higher demands on the bearing capacity of foundation piles.

[0003] Static load testing of piles involves gradually applying loads to the top of the pile and testing the settlement of the pile top under different load weights. By analyzing the real-time settlement data, the compressive bearing capacity of the pile is obtained. However, the methods for applying loads during static load testing rely heavily on the experience of staff. The authenticity and accuracy of the load data are greatly influenced by human factors and lack effective supervision, making it prone to falsification and compromising the objectivity and impartiality of the test. This reduces the reliability of the static load test results, thus requiring improvement. Summary of the Invention

[0052] The present application will be further described in detail below with reference to the accompanying drawings.

[0053] In one embodiment, such as Figure 1 As shown, this application discloses a loading method for static load testing of foundation piles, which specifically includes the following steps:

[0054] S10: Obtain the static load plane information of the foundation pile, and obtain the placement information of the load to be applied based on the static load plane information.

[0055] In this embodiment, static load plane information refers to the plane information of the platform on the pile to be tested for compressive static load, which is used to place the load, and the load placement information refers to the specific location where the load is placed on the platform.

[0056] Specifically, when conducting static load tests on foundation piles, camera equipment can be used to photograph and identify the static load platform on the foundation pile to be tested, thereby obtaining the planar information of the static load platform. For example, the planar information of the foundation pile refers to the shape of the static load platform, such as square or circular, as well as the area of ​​the shape, all of which are static load planar information.

[0057] Furthermore, utilizing the static load plane information of the foundation piles to obtain the specific location information of each load placed on the platform can be effective.

[0058] S20: Construct a load increase route based on the load placement information, and increase the load on the foundation piles based on the load increase route.

[0059] In this embodiment, the load increase route refers to the sequential route of the locations where the load is placed.

[0060] Specifically, by utilizing the information on the placement location of the load to be applied, a load increase path is planned. The load is then applied to the static load platform of the pile through the load increase path. Based on the corresponding placement location information, the load is accurately placed on the static load platform of the pile, thereby improving the accuracy of load application during the static load test of the pile.

[0061] S30: Obtain pile settlement data and pile bearing time data, obtain pile bearing data according to the load quantity, and fit a pile bearing management curve based on the pile bearing time data, pile settlement data and pile bearing data.

[0062] In this embodiment, the pile settlement data refers to the settlement depth value when the pile settles, the pile bearing time data refers to the time from when the pile begins to bear load to when settlement occurs, the pile bearing capacity data refers to the data of the load force borne by the pile, and the pile bearing capacity management curve refers to the curve used to analyze the relationship between the settlement depth of the pile and the load force and the time of action.

[0063] Specifically, after the load is placed on the static load platform of the pile, the pile will settle after being subjected to a certain force. The depth of the settlement and the duration of the load are recorded. Combined with the specific force of the load currently being applied to the pile, a relationship curve is fitted to analyze the compressive strength of the pile.

[0064] S40: Analyze the pile bearing capacity management curve to obtain the ultimate compressive bearing capacity data of the pile.

[0065] Specifically, by analyzing the pile bearing capacity management curve, the ultimate compressive bearing capacity data of the pile is obtained, and then the compressive bearing capacity of the pile is analyzed. When the pile bearing capacity management curve has no obvious inflection point, the load value corresponding to the total settlement at the top of the pile of 40 mm can be taken as the ultimate compressive bearing capacity of the pile. For the bearing capacity management curve of the gradually changing pile, the load corresponding to the settlement of 40-60 mm can generally be taken. For large-diameter piles, the load value corresponding to the settlement of 0.03-0.06D (D is the diameter of the pile, with the lower value for large pile diameters and the higher value for small pile diameters) can be taken. For slender piles (l / d>80), the load corresponding to the settlement of 60-80 mm can be taken.

[0066] In this embodiment, during the static load test of the foundation pile, the static load platform of the foundation pile to be tested can be identified using a camera device to obtain the static load plane information of the foundation pile. Based on the static load plane information of the foundation pile, the placement position information of the load to be applied is obtained. Using the placement position information of the load to be applied, a load increase path is planned, and the load is applied to the static load platform of the foundation pile through the load increase path. Furthermore, according to the corresponding placement position information, the load is accurately placed on the static load platform of the foundation pile, thereby improving the accuracy of load application during the static load test of the foundation pile. After the load is placed on the static load platform of the foundation pile, the data is obtained through... Data on pile settlement caused by pile settlement, pile bearing time, and the bearing capacity of piles of different numbers are used to fit a pile bearing management curve. By analyzing the pile bearing management curve, the ultimate compressive bearing capacity of the pile is obtained, and the compressive bearing capacity of the pile is analyzed. In the static load test of the pile, the addition of load is achieved by analyzing the static load platform of the pile and placing it scientifically and accurately on the static load platform of the pile. This improves the accuracy of the applied load during the static load test, thereby improving the accuracy of the static load test results.

[0067] In one embodiment, such as Figure 2 As shown, in step S10, the static load plane information of the foundation pile is obtained, and the placement information of the load to be applied is obtained based on the static load plane information. Specifically, this includes:

[0068] S11: Obtain the load placement starting point based on the static load plane information, and construct a two-dimensional plane coordinate system based on the load placement starting point.

[0069] In this embodiment, the load placement starting point refers to the location information of the first load placement point.

[0070] Specifically, by identifying the static load plane information of the foundation pile, the specific shape and size of the static load platform of the foundation pile can be determined. Taking the center point of the shape as the first load placement point can ensure that the initial stress on the foundation pile is uniform. A two-dimensional plane coordinate system is established with the first load placement point as the origin.

[0071] S12: Obtain load placement coordinate information according to the two-dimensional plane coordinate system, and obtain the load placement position information based on the load placement coordinate information.

[0072] Specifically, the coordinate information of the next load to be placed is obtained using the two-dimensional plane coordinate system, and the placement information of the load to be applied is obtained using the coordinate information, so that the next load can be accurately placed in the accurate position.

[0073] In one embodiment, such as Figure 3 As shown, before step S10, the loading method for the static load test of the pile compressive strength further includes:

[0074] S101: Obtain a regional image of the pile to be tested under static load, and input the regional image into a preset image recognition model to obtain the static load platform feature information.

[0075] In this embodiment, the area image refers to the image information surrounding the pile to be subjected to static load testing, and the static load platform feature information refers to the feature points of the pile's static load platform.

[0076] Specifically, among the collected images of the area surrounding the foundation pile, there will be images of static load platforms that do not belong to the foundation pile, such as soil, building materials, gravel and sand in the surrounding environment. The collected images of the area surrounding the foundation pile are processed by a preset image recognition model to remove obvious abnormal images, thereby obtaining the feature points of the static load platform of the foundation pile.

[0077] S102: Identify the static load platform area of ​​the pile to be tested for static compressive load based on the static load platform feature information.

[0078] Specifically, the static load plateau feature information of the foundation pile is identified by using an image recognition model on the regional image. The image recognition model can filter out redundant images in the regional image, and the static load plateau region of the foundation pile is identified and fitted by using the obtained static load plateau feature information. Then, the static load plateau information of the foundation pile can be obtained through the static load plateau region.

[0079] In one embodiment, such as Figure 4 As shown, in step S20, a load increase path is constructed based on the load placement information, and the load on the foundation piles is increased based on the load increase path. Specifically, this includes:

[0080] S21: Obtain the weight value of the placement location information of the load to be applied, and sort the placement location information of the load to be applied based on the weight value.

[0081] Specifically, after placing the first load, the weight value of the placement position information of the load to be applied is obtained. The weight value of the placement position information of the load to be applied is used to arrange the position information of the next load to be placed, so as to obtain the sorted placement position information of the load to be applied from primary to secondary.

[0082] S22: Fit the load increase path based on the sorted information of the placement positions of the loads to be applied.

[0083] Specifically, the load increase path is fitted based on the sorted information of the placement of the loads to be applied, and the load on the foundation piles can be increased according to the specified load increase path, so as to achieve a more scientific load increase on the foundation piles.

[0084] In one embodiment, such as Figure 5 As shown, after step S30, that is, after acquiring pile settlement data and pile bearing time data, acquiring pile bearing data based on the load quantity, and fitting a pile bearing management curve based on the pile bearing time data, pile settlement data, and pile bearing data, the loading method for the pile compressive static load test further includes:

[0085] S301: Calculate the fatigue damage parameters of the pile based on the pile bearing capacity data and pile settlement data.

[0086] In this embodiment, the fatigue damage parameter of the foundation pile refers to the health parameter value of the foundation pile that is prone to damage.

[0087] S302: Compare the fatigue damage parameters of the foundation pile with the preset health parameter threshold of the foundation pile, and adjust the load increase amount according to the comparison result.

[0088] Specifically, by analyzing and calculating the load-bearing and settlement data of the foundation piles, the health parameter values ​​of the foundation piles under the current load conditions can be obtained. The obtained fatigue damage parameters of the foundation piles are compared with the preset health parameter thresholds of the foundation piles. By appropriately adjusting the increase in load based on the comparison results, the health of the foundation piles can be effectively protected during the static load test of the foundation piles, and damage to the foundation piles can be prevented.

[0089] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
