Abstract

The invention provides a triaxial compression rheological test system capable of simulating an engineering geological environment, belonging to rock material compression experimental facilities. The remarkable characteristics of the invention are as follows: a test chamber in the triaxial compression rheological test system capable of simulating the engineering geological environment can depend on a normal rheological compression test device to realize the analogue simulation of the variations of a temperature field, a humidity field and a chemical field in the engineering geological environment by utilizing a humidifier, a heater and a fluid tank. The device fundamentally solves the problems of larger deviation of rock mechanics parameters obtained by a laboratory test and a field in-situ test and analogue simulation of a geotechnical wall-rock multi-field coupling environment. The test system has compact structure and low cost, is rather easy to install and dismount test pieces, detectors, pipelines and lead wires, and has stronger adaptability on the test pieces with different lithologies and sizes, thereby providing a set of complete technology and means for the study on the mechanical behavior of the wall-rock stability under a complex engineering geological condition.

Description

technical field [0001] The patent of the present invention relates to a rheological deformation test of rock mass, specifically a rock rheological deformation test system imitating engineering geological environment, especially suitable for multi-field coupling rheological deformation and failure mechanics test of engineering rock mass. [0002] At present, the physical models of rock mechanics research are mostly indoor ideal test environments, and their simulation conditions cannot represent the real physical, chemical and mechanical environment conditions of the formation, and there will be certain errors between the obtained results and the actual engineering results. Therefore, the development and application of the triaxial compression rheological test system for simulating engineering geological environment is of great significance. At present, there is no triaxial compression rheological test system for simulating geological environment at home and abroad. Background...
