Abstract

The invention belongs to the field of studies on stability of rock and earth masses under a multi-field coupling effect, and particularly relates to a thermo-hydro-mechanical multi-physical field coupling simulation experiment system suitable for the rock and earth masses and a use method thereof. The thermo-hydro-mechanical (THM) coupling simulation experiment system mainly comprises a monitoring mainframe, a triaxial pressure test mainframe, a heat pump control circulating system, a GDS pressure-volume controller group and a data collector; by carrying out gradual in-depth studies on influence of a mechanical unloading process on the mechanical properties and the hydraulic properties of the rock and earth masses and the influence of temperature loads on the damage evolution law, the permeability and the thermal conductivity of the rock and earth masses on the surrounding of a chamber, and the interaction and mutual influence conditions between of a stress field and a seepage field (HM), between the stress field and a temperature field (TM) and between the seepage field and the temperature field (TH) are disclosed.

Description

technical field [0001] The invention belongs to the field of stability research under multi-field coupling effects of rock and soil bodies, and in particular relates to a simulation test system suitable for rock and soil body temperature-seepage-stress multi-physics field coupling and a use method thereof. Background technique [0002] Since there is no generalized multi-field coupling theory and numerical analysis method for complex rock-soil mass in China to study the physical and mechanical properties of rock-soil mass multi-field coupling state, in order to solve problems such as the stability of engineering rock-soil mass. Most of the research work that has been done is focused on the theory and numerical simulation of the three-field coupling mathematical model of rock and soil, but there are few related experimental studies. [0003] The development of this test system can not only provide experimental support and guidance for theoretical research and numerical simula...
