Abstract

The invention discloses a temperature-pressure coupling bidirectional electromagnetic loading dynamic compression-shear experimental device and a testing method. The device comprises a supporting seat, a loading rod, a dynamic loading device, a static loading device, a temperature control mechanism and a dynamic compression-shear mold arranged in the temperature control mechanism. By arranging the temperature control mechanism, the device can perform temperature rise and heat preservation on the test sample before and in the dynamic and static combined compression-shear test, so that dynamic and static combined compression-shear test research on the test sample under the condition of temperature-pressure coupling is realized. The problem that in the prior art, dynamic compression-shear tests of rock-like solid materials such as rocks and concrete under different temperature and static prestress environment conditions cannot be carried out is solved, so that test conditions are closer to real occurrence and working conditions of the rock-like solid materials such as rocks and concrete under a natural environment; therefore, a test result can be closer to a real situation, and the device and method have more scientific value and practical significance for engineering practice.

Description

technical field [0001] The invention relates to the technical field of dynamic compression-shear testing of solid materials such as rocks and concrete, and in particular to a dynamic compression-shear experimental device and a testing method for temperature-pressure coupled bidirectional electromagnetic loading. Background technique [0002] With the increasing demand for the development and utilization of energy resources and transportation, more and more deep rock engineering (deep mining, tunnels, water conservancy, geothermal development, and nuclear waste storage, etc.) The construction of areas with active disturbance causes the underground rock mass in these areas not only to bear the effect of axial static stress, but also often affected by dynamic loads such as earthquakes, explosions, and engineering disturbances; in addition, deep rock mass engineering is also accompanied by high ground temperature. Especially in the development and utilization of deep hot dry roc...
