某水电站坝肩工程边坡稳定性三维数值模拟分析

3D Numerical Simulation Analysis for Engineering Slope Stability of a Hydropower Station Abutment

根据对某水电站坝肩工程边坡详细的野外实地调查,通过查阅和整理大量的资料总结出工程区边坡工程特性,得到边坡稳定性定性评价;利用FLAC3D数值模拟方法对开挖边坡稳定性进行了数值模拟分析研究。根据边坡稳定性定性分析和数值模拟计算分析结果对坝肩开挖边坡稳定性提出综合分析评价,得出结论:整个坝肩边坡在开挖状态下整体处于稳定状态,为坝肩边坡安全开挖和治理提供了依据。

According to the detailed field investigation for the engineering slope of a hydropower station abutment and through consulting mass data,the slope excavation engineering characteristics about the project are summed up here,and the stability of the excavation slope is evaluated qualitatively.The FLAC3D numerical simulation method is used to simulate and analyse the excavation slope＇s stability.According to the stability analysis and numerical simulation results of the slope,the comprehensive analysis and evaluation of the slope are made.The conclusion is that the whole abutment engineering slope is steady in the process of excavation,which would provide basis for the safety excavation and management of abutment engineering slope.
