Abstract

A rock mudification process simulation device under dynamic water circulation and load conditions, including a water flow control device, the water flow control device communicates with the circulation device through the mudification simulation device; There are upper permeable stones and lower permeable stones matched with the rock samples, fixed baffles with loading devices are matched with the upper permeable stones, and multiple permeable holes are evenly distributed on the side wall of the inner chamber; the circulation device includes filters , the other end of the circulation pipe communicates with the second flow rate controller and the collector in turn through the filter. The present invention provides a rock mudification process simulation device and test method under dynamic water circulation and load conditions, which can solve the defect that the existing device cannot truly simulate the environmental conditions of the engineering rock mass in the rock mudification process simulation test, and improve The accuracy of the test results can also improve the efficiency, convenience and standardization of the test.

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. ...
