Abstract

This invention belongs to the field of geotechnical engineering and geological disaster prediction technology, and particularly relates to an atmospheric coupled degradation simulation test system for slopes. It includes a slope model box, a non-uniform thermal radiation field simulation system, a multiphase seepage system, a dynamic stress loading system, and a control calculation system. The non-uniform thermal radiation field simulation system simulates the surface temperature gradient and mineral thermal expansion effect caused by solar radiation. The multiphase seepage system simulates acid rain, snowmelt seepage, and dissolution reactions. The dynamic stress loading system accurately simulates crack propagation under seismic wave action. This invention integrates non-uniform thermal radiation field, multiphase seepage, and dynamic stress loading into one system, constructing a system capable of simulating the real degradation process of slopes under complex natural environments. It achieves coupled simulation of the three stages of "surface thermal cracking - internal erosion - dynamic response," providing an efficient test platform for slope stability research under complex environments.
