Abstract

The invention provides a multi-working-condition coupling landslide model test device. The device comprises a model frame assembly, a rainfall simulation assembly, a water flow scouring assembly and a lifting assembly; the model frame assembly is used for piling up a sample soil slope and simulating the reservoir water level lifting condition, the rainfall simulation assembly is arranged above the model frame assembly and used for simulating different rainfall intensities, and the water flow scouring assembly provides scouring water flow and water storage level for the sample soil slope in the model frame assembly; and the lifting assembly drives one end of the model frame assembly to lift to adjust the inclination angle. By adjusting the matching of clamping plates and the use of each component, the influence of rainfall, reservoir water level rising and falling, water flow scouring and other working conditions on the slope stability is simulated, so that the dynamic evolution process of slope instability under the coupling action of different working conditions is tracked, analyzed and researched, the test phenomena of slope damage under different influence factors are obtained, and the test possibility is provided for researching different instability mechanisms of the slope.

Description

technical field [0001] The invention relates to the technical field of slope engineering tests, in particular to a multi-working condition coupled landslide model test device. Background technique [0002] Landslide is a geological phenomenon in which the rock and soil mass on the slope slides along the sliding surface under the influence of adverse conditions. Due to its strong suddenness and great harm, it seriously threatens the safety of life and property of the people in mountainous areas. A natural disaster not to be underestimated. Most landslides are directly or indirectly related to water, commonly known as "ten slippery nine water", the impact of water on the slope is mainly manifested in the infiltration of rainfall, erosion of groundwater, rise and fall of reservoir water level, and erosion of the foot of the slope by water flow, etc. Wait. Therefore, it is of great significance to explore the influence of water on slope stability through experiments. [0003]...
