Manifold rock mass simulation test detection equipment

Abstract

The invention relates to manifold rock mass simulation test detection equipment which is provided with more than 3 test groups, each test group comprises an axial loading system, a pressure chamber, a confining pressure loading system and a detection data recording system, and all test groups can carry out different simulation test detections. By adopting the structure, test time can be saved. All test groups are connected with a computer system and are controlled by the computer system, the computer system receives data output by the axial loading system and the pressure chamber and compares the data with preset simulation data, sends a regulation command to the axial loading system and the confining pressure loading system according to the comparison result to enable main pressure and confining pressure of the pressure chamber to be kept stable, and automatically records a detection result. The data sampling speed and the response speed of the computer system are high, therefore, the success rate and the accuracy of the test are high.

Description

Multiple rock mass simulation test testing equipment technical field The invention relates to a device for testing and detecting changes in physical properties of rock mass by simulating environment. Background technique The natural stress state of the crustal rock mass is closely related to human engineering activities. It is not only an important factor determining regional stability, but also often has a direct impact on the design and construction of various buildings. Practice has shown that the excavation of rock mass during the construction of surface and underground projects in high-stress areas can often cause a series of deformation and failure phenomena in the interior of the rock mass associated with unloading springback and stress release. The result is Not only will it deteriorate the engineering geological conditions of the foundation or slope rock mass, but the action itself will sometimes cause direct damage to buildings. It is an important task of engin...

Problems solved by technology

Several series of products have been developed in China based on the "triaxial tester" for rock mass simulation test detection, but these products simulate the natural environment, the stress status of the sample in the deep crust and the creep properties of the rock (also The determination of "brittle-ductile critical strain rate" (called rock rheology) is not accurate enough

In addition, when using one host in the test, only one test can be done at a time (some tests need more than 180 days)

Since the deep underground is an invisible environment, detection tests and comparison tests
