Abstract

The invention provides an experimental device and method for simulating the damage effect of an earthquake on a reservoir bank slope rock mass. The upper part of a base abutment is provided with earthquake simulation equipment for simulating the earthquake, the top of the base abutment is fixedly provided with a top box body, the top box body is in a hexahedron shape, and the top of the top box body is provided with composite meteorological simulation equipment; a test cabin is arranged in the top box body and is positioned at the lower part of the composite meteorological simulation equipment; a water vapor circulation system used for simulating weather in the device is arranged under the test cabin; a CT scanning system for rock detection and a control system of the whole device are arranged between the side wall of the test cabin and the outer wall of the top box body; and a circular top cover for internal water and electricity to pass is arranged at the top of the test cabin. The influence of a single extreme weather on the reservoir bank rock mass can be researched, and the influence of snowfall, storm wind and other composite weather conditions on the reservoir bank rock mass can also be simulated.

Description

technical field [0001] The invention belongs to the field of civil engineering scientific research devices, and in particular relates to an experimental device and method for simulating the damage effect of earthquake action on reservoir bank slope rock mass, and especially relates to a built-in CT detection function for simulating the impact of earthquake action on reservoir bank under complex meteorological conditions. Experimental device and method for slope rock mass damage. Background technique [0002] Among the existing experimental devices, there are still relatively few experimental devices and equipment related to the damage of the rock mass of the reservoir bank slope by earthquake action, especially when considering the effects of various complex and extreme climate conditions, and adding the damage detection system at the same time. Devices are few and far between. The design of this device can directly simulate and detect the damage of the reservoir bank slope...
