Abstract

The high and steep stratified rock slope with steep top and gentle bottom is typical in western China. This study investigated this kind of slope's deformation patterns and failure mechanisms induced by step-by-step excavations. FLAC3D simulated the excavation process according to the actual situation (the first three phases) and planned excavation order (the last two phases). The reasonableness of the model was tested by comparing the simulation results of the first three stages with the actual slope form. The failure characteristics were analyzed by simulation results of the last two phases. During the entire excavation, deformation can be summarized as "slip-bend-shear", where the most dangerous slip surface of the composite style is developed gradually into the slope. The current mining plan probably fails to avoid landslides, and some treatments such as reinforcing the toe of the slope, bolt reinforcement, and drainage are necessary.
