Description

Technical Field

[0002] Soil and rock bearing capacity is a core indicator in geotechnical engineering for measuring the load-bearing capacity of foundations or rock masses. It is mainly divided into two categories: ultimate bearing capacity and allowable bearing capacity. Field testing directly measures the mechanical properties of natural soil and rock layers in the field to determine their mechanical parameters. The basic method for field testing is load testing, which simulates the stress state of a building foundation. The test results are relatively intuitive, but the testing method is time-consuming and labor-intensive, and can only be used for some representative strata. Indoor testing involves processing samples according to the test items and simulating and effectively testing their physical and mechanical properties. The test results are relatively accurate. However, indoor testing is less intuitive than field testing. Existing soil and rock bearing capacity testing devices require manual cleaning of the waste material on the test platform surface after the bearing capacity test, which is time-consuming, has poor cleaning effect, and affects the overall testing efficiency. Furthermore, the large volume of rock waste occupies a lot of space, affecting storage capacity. Additionally, before the bearing capacity test, soil and rock blocks need to be manually placed in the center of the test plate, which is time-consuming and has low accuracy.
