Abstract

The invention discloses a device and a method for simulating a mechanism of reservoir bank side slope rock damage caused by rainfall, light and wind. The device comprises an artificial rainfall system, a lighting system and a base, wherein a water outlet is formed in the base; an experimental instrument casing is arranged on the base; the artificial rainfall system and the lighting system are respectively assembled with the experimental instrument casing through grooves; a sample bracket is arranged in the experimental instrument casing; rock sample plates are arranged on the sample bracket; fan blade wheels are mounted in the middle of the experimental instrument casing and on a screw rod; the screw rod is connected with a motor. Through adoption of the device and the method, rock damage cause by not only rainfall but also two kinds of natural erosion, namely light and wind, can be simulated, and convenience is provided for rock damage mechanism research.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, in particular to a device and method for simulating the damage mechanism of rainfall, sunlight and wind to rocks on reservoir bank slopes. Background technique [0002] In the field of geotechnical engineering, especially in rock engineering, under the joint action of rainwater, sunlight and wind erosion, the properties of the internal structure of the rock have been greatly affected, making the rock suffer damage. At present, the existing physical model test equipment for simulating artificial rainfall reservoir landslides can better simulate the real situation and collect test data conveniently. However, it cannot simulate the influence of rainfall on the slope rocks of the reservoir bank, and does not consider the effects of sunlight and wind on rock and soil erosion. Contents of the invention [0003] The present invention provides a device and method for simulating the damage mech...
