One earthquake has always been very concerned about natural disasters caused by the earthquake debris slope landslide mix is one of the great threats to people's lives and property safety of geological disasters. Due to the heterogeneity of soil-rock mixed slopes, the problem of slope landslides under earthquake action has become the focus of research. In order to solve such problems, this study using the thermodynamic principle of earth-rock mixture slope under the action of the earthquake destructive is analysed, with the first law of thermodynamics as the foundation of earth-rock mixture slope destructive research data in the calculation, and then using FLAC3D program to establish a three-dimensional model of earth-rock mixture slope in the role of dynamic loading instead of seismic wave on the slope, through the relevant formula of earth-rock mixture slope under dynamic load, and earth-rock mixture shear strength index of slope and slope safety factor. The results show that the proportion and shape of block stones have great influence damping ratio of the slope. The greater the cohesion of the mixed slope is, the higher the safety factor is. The greater the angle of internal friction is, the greater the safety factor is. When the internal friction angle was 42°, cohesion was 17KPa, 43°, 44°, 15KPa, 45°, and 46°, respectively, the safety factor of the soil and stone mixed slope could reach 1.05.
