Abstract

A rock shearing-influent couple test system comprises a shearing box, a test force loading and displacement testing device, an open measurer and a computer, wherein the shearing box comprises a water inlet channel and a water outlet channel. The invention is characterized in also composed of an influent detector comprising a water inlet device and a water outlet flux measurer, the water inlet device is communicated with the water inlet of the water inlet channel, the water outlet flux measurer is communicated with the water outlet of the water outlet channel. When processes rock shearing-influent couple test, the invention can freely change the volume and change method of tangent force, normal force and water pressure, as well as obtain the open change, tangent displacement and flux, while the data can real represent the force state, without multiple devices, to reduce cost, save time, save following data treatment time, and improve working efficiency.

Description

technical field [0001] The invention relates to a test system for rock joint shear-seepage coupling test. Background technique [0002] When the rock mass in nature is subjected to external force, structural surfaces such as joints and fissures will be produced. When the intact rock in a certain area is broken by external force, a pair of joint surfaces will be formed. There are usually two problems in the shear-seepage coupling test of rock joints at home and abroad: too small seepage water pressure and radial water flow. The osmotic water pressure value is too small, and the water head height is only more than 2m. Under low osmotic pressure, the sealing of the shear box is relatively easy to realize, but the maximum water head height in actual engineering even exceeds 1000m, and it is difficult to seal the shear box; while the radiation The seepage mode of the flow is to inject water from the center of the joint surface to flow to the surroundings. As long as the continuo...
