Abstract EN
The present study aims to elucidate the problem of a rock mass structural plane with a range of damage degrees and the numerical model selection for analysis of a slope with multiple sliding surfaces.
Based on the relative displacement between blocks, the dynamic strength reduction-discontinuous deformation analysis (hereinafter referred to as DSR-DDA) method is proposed for studying slopes with multiple sliding surfaces.
The slope-slider classic case was used to test the displacement threshold.
The model was applied to the stability analysis of multiple sliding surfaces of a high rock slope in the Fushun West Open-Pit Mine.
The results show that when the displacement threshold is set to 1 mm, the error between the DSR-DDA results and the theoretical solution is within 0.5%, which satisfies the calculation requirements.
The most dangerous slip surface in the Fushun West Open-Pit Mine slope was identified.
Based on the numerical slope model after the first landslide, the position of the secondary slip surface was then identified.
The failure mode is traction sliding failure, and the middle and lower oil shales play a key role in the slope stability.
This study recommends that mining of the remaining oil shale should stop to avoid causing large-scale landslides in the upper part of the slope and landslides at the pit-city boundary.
