Abstract

The invention relates to a testing device of a rock-soil body in-situ strength bearing plate and a usage method of the testing device. The testing device comprises a PC, a tester, a power mechanism, a bearing unit, a data collection and feedback unit and an assisted supporting structure; the PC and the tester are connected with each other, and a control module in the tester is a single chip microcomputer system; the power mechanism consists of a power generator, a motor driver, a moment motor, a speed reducer, a coupling and a jack; the bearing unit consists of a stress transmitting pillar and a bearing plate; the data collection and feedback unit is mainly provided with a rotary encoder and a pressure sensor. The device is assembled into a whole in a buckling manner, the rigid loading requirement needed by testing can be guaranteed; and in moving, the testing device can be conveniently moved and transported after being disassembled into small units. The usage method can be controlled by a program online or offline, the testing mode can be selected from a time mode, a displacement mode and a pressure bearing mode. The testing device and the usage method have the advantages that the mode switching is flexible, the testing process, data sampling and storage are automatic, and the like, and the testing efficiency and the quality reliability of testing data can be improved.

Description

technical field

[0001] The present invention relates to an in-situ strength bearing plate test device for rock and soil mass and its use method, in particular to a pressure-bearing plate test device and its use method related to the in-situ strength test of rock and soil mass, which is a test mode The invention discloses an automatic pressure-bearing plate test device and a use method which are adjustable, disassembled and moved conveniently, and belong to the field of in-situ test of geological engineering rock and soil. Background technique

[0002] With the increase of engineering construction and the continuous increase of construction scale, various geological disasters such as landslides, debris flows, subsidence, etc. have become more and more frequent, and the stability of rock and soil has been increasingly recognized by scholars and engineers at home and abroad. focus on. The stability of rock and soil depends on its own mechanical properties, so the relationship ...
