介绍大寨河一级电站沉砂池边坡的特征，采用刚体极限平衡法对边坡进行数值仿真分析，评价边坡在天然与开挖无支护、加支护及电站正常运行等工况下的稳定性分析及评价，并对各典型剖面进行加固措施研究和支护方案设计，使边坡治理更趋科学合理。该电站已经发电1年，边坡稳定，说明边坡地质参数取值可靠，计算合理。
介紹大寨河一級電站沉砂池邊坡的特徵，採用剛體極限平衡法對邊坡進行數值倣真分析，評價邊坡在天然與開挖無支護、加支護及電站正常運行等工況下的穩定性分析及評價，併對各典型剖麵進行加固措施研究和支護方案設計，使邊坡治理更趨科學閤理。該電站已經髮電1年，邊坡穩定，說明邊坡地質參數取值可靠，計算閤理。

The paper deals with the characteristics of the slope of the desilting basin of the Dazhaihe -I hy-dropower plant .The rigid body limit equilibrium method was employed to make the numerical simulation analysis of the slope to analyze and to assess its stability respectively under the natural condition ,the con-dition of excavation without support ,the condition of excavation with support and the condition of normal operation of the hydropower plant .And the reinforcing measures and the supporting scheme were also studied and designed for various typical profiles of the slope so that the control of the slope could be more scientific and reasonable .The Dazgaihe-I hydropower plant has been under operation for 1 year and the slope has been stable ,w hich means that the selected geological parameters of the slope are reliable and their calculation are rational .
