Abstract

This Based on the stope in HeBei province, the sliding failure mode and treatment measure after the excavation of the stope is discussed. The RMR methods and the GSI methods are both used to estimate the mechanical parameters of the rock mass, and the smaller parameters are selected for the stability calculation. The numerical simulation of the slope excavation by finite element is carried out, and the development of the displacement and plastic zone during the excavation are analyzed. Furthermore, the stability analysis of the excavated slope is carried out, and the results showed the safety factors cannot meet the standard requirement. Then the bolt support are used to reinforce the excavated slope, and the calculation results show that the safety factors of the reinforced slope can meet the requirement of the relative standards.
