Abstract

The invention relates to a geological disaster physical experiment device, and particularly relates to a physical experiment device for exploring a rainfall-induced dangerous rock mass caving mechanism. The device comprises a fractured dangerous rock body to be tested, dangerous rock body deformation data synchronous acquisition modules, a hydraulic gradient regulator, a rotary adjustable rainfallsimulation system, a dangerous rock body local data processing module, a small double-row in-line signal receiving and transmitting device, a local data receiving center, a full-automatic high-speedcamera, rock and soil debris and a rainfall receiving tank. The dangerous rock body deformation data synchronous acquisition modules are arranged around the periphery of the crack of the dangerous rock body; a gas spring hydraulic supporting rod used for gradient adjustment can actively adjust the local slope surface where the dangerous rock body is located; and the rotary adjustable rainfall simulation system uniformly sprays water at multiple angles to simulate the influence of natural rainfall on the dangerous rock mass caving mechanism. By simulating natural rainfall, a mechanism of inducing dangerous rock mass caving by rainfall is observed, related data of cracks of the dangerous rock mass is collected and recorded, and statistical analysis is carried out on the related mechanism.

Description

technical field [0001] The invention relates to a physical experiment device for geological disasters, in particular to a physical experiment device for exploring the caving mechanism of dangerous rock masses induced by rainfall. Background technique [0002] Dangerous rock mass refers to some rock mass that has not yet collapsed, but has the main conditions for collapse, and the precursor phenomenon of collapse has appeared, so it is predicted that a collapse may occur in the near future. Dangerous rock mass is a potential collapse mass. my country is a country with complex mountain geomorphology. Dangerous rock collapse is a common geological disaster in mountainous areas. Dangerous rock collapse has the characteristics of strong suddenness and great destructive power, which seriously threatens traffic arteries and the normal life of mountain residents. Production and life; In my country, a large number of casualties and major economic losses are caused by the collapse of ...
