Abstract

The invention relates to a geomechanical model test device adopting a self-balancing double-loading mode and a test method. The geomechanical model test device comprises a force bearing rack, a base plate, a bottom plate, a counter-force plate, a gravity balancing weight, bolts, an isolation plate, a hydraulic jack, a hydraulic workstation and a servo controller. The force bearing rack is formed by welding rectangular square steel, the rigidity requirement of the device is met, and meanwhile the isolation plate is convenient to install and place. The base plate is located above a test body andbelow the jack (balancing weight), and therefore it is guaranteed that loads are evenly transmitted to the test body in the test process. Connecting holes are reserved in the force bearing rack and the counter-force plate, and the force bearing rack and the counter-force plate are spliced through the bolts, so that the requirements of tests on different loading modes are met. The device is simplein structure and reusable, migration of an experimental device can be realized without position limitation, and the device can realize quick and accurate loading and can also realize a long-term stable loading and unloading mode.

Description

technical field [0001] The invention relates to a geomechanics model test system, in particular to a self-balancing double-loading mode geomechanics model test device and method. Background technique [0002] With the development of economy and the increase of traffic volume, my country has become the country with the largest scale, largest number and fastest construction speed of tunnel projects in the world. Due to the complexity of geological conditions, the periodicity of ambient temperature and the characteristics of structural materials, it is very easy to cause disasters such as landslides in the tunnel construction stage, cracking and falling of linings in the operation stage. Therefore, mastering the deformation law and failure mechanism of tunnels under different loads and factors and how to take effective measures have become one of the core issues restricting the development of tunnels. For these problems, there are mainly theoretical analysis, numerical simulat...
