AI Technical Summary

Technical Problem

The existing slope instability mechanism simulation experimental device is difficult to accurately adjust the vibration parameters and rainfall intensity on the slope foot, slope top and both sides of the slope body, and cannot effectively simulate the impact of different terrain and vegetation distributions on slope instability, resulting in a decrease in experimental accuracy.

Method used

An experimental device for simulation of slope instability mechanism of lower slope coupling of earthquake and rainfall was designed. By accurately controlling the coordination position and state of the cam and the vibrating convex plate, the vibration amplitude of the experimental model is adjusted, and by flexibly controlling the rotation period of the unidirectional long screw, the spray intensity is adjusted, and slope instability at different positions and under different rainfall intensity is simulated.

Benefits of technology

The precise adjustment of the slope vibration amplitude and spray intensity is achieved, and the slope instability process under multiple coupled conditions of earthquake and rainfall can be simulated, which improves the authenticity and effectiveness of the experiment, and can more comprehensively reflect the comprehensive effect of complex environmental factors on slope stability in actual geological disasters.

Abstract

The embodiment of the invention provides a slope instability mechanism simulation experiment device under the earthquake and rainfall coupling effect, and relates to the technical field of earthquake simulation equipment. The slope instability mechanism simulation experiment device under the earthquake and rainfall coupling effect comprises a model storage mechanism, a driving transmission mechanism and an adjusting mechanism, the driving transmission mechanism is located at the lower end of the model storage mechanism and enables a model in the model storage mechanism to vibrate, and the adjusting mechanism is located at the lower end of the model storage mechanism and enables the model in the model storage mechanism to vibrate. The adjusting mechanism is located at the lower end of the model storage mechanism and located in the middle of the transmission mechanism, and the transmission mechanism moves upwards and drives the adjusting mechanism to rotate. According to the device, the matching position and state of the cam and the vibration convex plate can be accurately changed, so that the vibration amplitudes of the slope toe, the slope top and the two sides of the slope body of an experimental model are accurately adjusted, the requirements for slope vibration amplitude simulation under different experimental conditions are met, and the influence of the vibration amplitudes on a slope instability mechanism can be deeply researched.
