Abstract

The invention discloses a rock argillization process simulation process under a movable water circulation and loading condition. The device comprises a water flow control device, wherein the water flow control device is communicated with a circulation device through an argillization simulation device; an inner cabin comprises a container body of which the top end and the bottom end are open; an upper porous stone and a lower porous stone, which are matched with a rock test specimen, are arranged in the container body; a fixing baffle with a loading device is cooperated with the upper porous stone; a plurality of permeable holes are evenly distributed on the side wall of the inner cabin; the circulation device comprises a filter; and the other end of a circulation pipe is communicated witha second flow rate controller and a collector through the filter in sequence. By use of the rock argillization process simulation process under the movable water circulation and loading condition, andthe test method, the defects that an environment condition where an engineering rock mass is positioned can not be truly simulated in a rock argillization process simulation process simulation test can be eliminated, the accuracy of a test result is improved, and the efficiency, the convenience and the normalization of the test also can be improved.

Description

technical field [0001] The invention relates to the field of testing of geotechnical engineering, geological engineering, mining engineering, etc., in particular to a rock mudification process simulation device and testing method under dynamic water circulation and load conditions. Background technique [0002] A large number of engineering rock masses will be muddy under the action of water, especially soft rocks are very easy to muddy when exposed to water. Once mudification occurs in engineering rock mass, it will cause serious engineering safety accidents, even disasters. The destruction of a large number of large bedding rock slopes is mostly caused by mudification of weak rock strata, such as the Shanshugou landslide and Anlesi landslide in the Three Gorges Reservoir area, the Tiantai Township landslide in Sichuan Province, and tunnels and other underground projects due to soft rocks. Disaster events such as roof collapse and roof fall caused by rock mudification. ...
