Study on Slope Stability Analysis and Management Scheme of a Hydropower Station
[Purposes]In order to eliminate the geological hazards of a hydropower station slope with po-tentially unstable rock mass in Xizang,it is necessary to study its stability and propose a treatment plan.[Methods]Based on the results of geological investigation and structural analysis of the slope,three typi-cal profiles were selected to construct a two-dimensional slope,and the stability of the slope under three different working conditions was calculated by the limit equilibrium method.[Findings]The stability cal-culation results show that:the stability coefficients of the three typical profiles under the three working conditions are all greater than 1.2,and the slope is in a stable stage;according to the stability calculation results,the management measures of lattice beam+prestressed anchor cable+active protection network+monitoring are proposed.[Conclusions]This study calculates the stability of the slope and puts for-ward the management scheme,which can provide reference for similar projects.
