Abstract

The invention relates to the technical field of rock test equipment, in particular to circulating water pressure direct shear equipment for temperature seepage coupling, which is characterized in that a high and low temperature box (2) is placed in a loading system (1); the seepage shear box (4) is arranged in a cavity of the high-low temperature box (2) through a limiting device (5), penetrates through the high-low temperature box (2) through a first pull rod (411) and a second pull rod (422) which are located on the two sides of the seepage shear box (4), and is connected with a tangential fixed piston (14) and a tangential stroke piston (15) of the loading system (1). The tangential stroke piston (15) can be used for transversely loading a test block in the seepage shear box (4), and the normal stroke piston (13) can be used for normally loading the test block placed in the seepage shear box (4). And the test temperature in the seepage shear box can be ensured through the high-low temperature box (2).

Description

technical field [0001] The invention relates to the technical field of rock test equipment, in particular to a circulating water pressure direct shearing equipment used for temperature seepage coupling. Background technique [0002] The safety of the reservoir slope is of great significance to the long-term safe operation of the hydropower station. The stability of the slope structure of the reservoir is mainly controlled by the rock structure surface. The fluctuation of the reservoir water caused by the rainfall and the adjustment of the reservoir water storage will cause great safety hazards to the safety of the joint surface. The existence of water will weaken the strength of the structural surface, and the fluctuation of the reservoir water will generate circulating water load on the structural surface, resulting in fatigue damage, especially for the long-term safety of the reservoir. On the other hand, reservoirs are mostly built in high mountains, and the temperature ...
