Problems solved by technology

The main problem is that the size of the model frame is fixed and non-uniform loading cannot be performed
[0006] (4) The fourth issue of "Underground Space" in 2004 introduced a frame-beam type model test bench system, which can carry out quasi-plane strain tests, but the lateral deflection of the bench is relatively large, which may easily cause the boundary conditions of the test to be broken. Change
[0008] 1) The size of the test device is fixed and cannot be adjusted

Abstract

A test system of 3D geologic mechanical model is composed of box testing device formed by connecting box cast steel component, angle element and chassis together through high strength bolts; hydraulic loading control system formed by variable ¿C load loading plate with thin jack at top, hydraulic loading control table and oil separator. It features that said loading plate is connected on left and right internal walls of box testing device through thin jack and said loading control table is connected to jack through oil separator and oil pipe.

Description

technical field [0001] The invention relates to a geomechanics model test system used in the fields of water conservancy, transportation, energy and mine engineering, in particular to a three-dimensional geomechanics model test system. Background technique [0002] From the beginning of this century, some countries in Western Europe began to conduct structural model tests, and gradually established similar theories. In the 1960s, experts headed by E.Fumagalli pioneered the engineering geomechanics model test technology in the Italian Structural Model Test Institute, and the test research ranges from elasticity to plasticity to the final failure stage. Subsequently, countries such as Portugal, the former Soviet Union, France, Germany, the United Kingdom and Japan also carried out research in this area. In China, since the 1970s, Wuhan University of Water Conservancy and Electricity, Tsinghua University, the Third Research Institute of the General Staff Engineering Corps, Sou...
