Abstract

The invention relates to the field of geological disaster research, in particular to a reservoir area hydro-fluctuation belt degradation simulation system. The device comprises an experiment box, a nuclear magnetic resonance signal processor for collecting proton energy level transition information of a sample excited and received in the experiment box, a flow controller for collecting and controlling physical quantity change in the experiment box, an air pressurizing and heating system for increasing the temperature in the experiment box, and a liquid nitrogen system for reducing the temperature in the experiment box, the water level control system is used for injecting water into the experiment box; the drainage system is used for draining liquid and reducing pressure in the experiment box; the upper computer is used for analyzing and processing all experiment data; according to the technical scheme, rock mechanical property changes of the hydro-fluctuation belt rock mass under different water levels, different pressures and different temperature environments, the destructive effect of pore water on the rock mass and the degradation effect of dry-wet circulation on the rock massare simulated, so that the ecological restoration capacity and the landscape reconstruction capacity of a bank slope of a reservoir area are improved, and the secondary geological disaster risk of thereservoir area is reduced; the geological disaster early-warning and forecasting capability is improved, and the life and property safety of people is guaranteed.

Description

technical field [0001] The invention relates to the field of geological disaster research, in particular to a degradation simulation system of a water-fluctuation zone in a reservoir area. Background technique [0002] Since the impoundment of the Three Gorges Reservoir area, the water level in the reservoir area has fluctuated periodically between 145 and 175m in elevation, forming a ebb and flow zone with a vertical drop of 30m. Under the periodic cycle of immersion in river water and rapid temperature changes, the quality, stress and rock mechanical properties of the rock mass in the bank-fluctuation zone will rapidly deteriorate, causing new geological disasters. For example, in the Qianjiangping landslide in 2003, the landslide blocked the Qinggan River and caused a huge wave of about 40 meters, causing more than 80 farmhouses and 4 factory buildings to be reduced to ruins; in 2008, the 175-meter-long experimental water storage in the Three Gorges Reservoir area At tha...

However, this invention can only provide video information of the entire landslide simulation process, and is not equipped with relevant detection sensors, so it cannot collect relevant parameters in the experiment

[0010] The contents disclosed in the above-mentioned patent documents are not a complete simulation system for the degradation of the water-fluctuation zone in the reservoir area, and cannot realize real-time monitoring and monitoring of the rock mechanical property changes of the rock mass in the water-fluctuation zone under different water levels, different pressures, and different temperatures.
