The reaction load applying device is reasonable and standard in structure, convenient for use, suitable for load application of foundation model tests with various specifications, convenient for control of applying modes and higher in precision.
Description
technical field [0001] The invention relates to the field of civil engineering tests, in particular to a reaction load applying device and a test method for foundation model tests. Background technique [0002] In geotechnical engineering, the stress conditions of foundations and foundations are often complex, and it is difficult to determine the performance of a certain form of foundations and foundations through simple theoretical calculations. In order to study the engineering performance of the foundation, people usually need to conduct model tests of different sizes. Applying load is a key step in model testing. Generally speaking, when people apply load, they usually need to continuously adjust the counterweight according to the different applied loads. The process is cumbersome, and the load cannot be accurately controlled. [0003] At the same time, the settlement of the foundation or the foundation under the given load often needs to be measured by other means, whi...
