Effect of Soil Creep on Yinwan Dump Stability

Considering the creep characteristics of loess floor dump, the traditional Mohr - Coulomb model and the improved Burgers creep model were used to research the failure mechanism of slope based on the features of the surface coal mine dump. Slope defor-mation characteristics of the actual situation and the simulation were compared. The slope stability in different failure modes was analyzed. The results showed that, considering the impact of the loess floor creep, the possible failure mode was foundation type landslide and displacement monitoring data was consistent with the high degree of site.
