石板滩滑坡地段路基边坡稳定性分析与加固措施

摘要

阐述了溪洛渡水电站库区石板滩滑坡概况,分析了石板滩滑坡形成机理,考虑了水位骤降、暴雨、地震等对路基边坡稳定性的影响。采用STAB2009程序对溪洛渡水电站库区石板滩滑坡地段路堑边坡和高路堤边坡的稳定性进行了分析,并提出石板滩滑坡地段路基边坡设计方案与工程措施。%The paper gives the overview of Shibantan landslide in the reservoir area of Xiluodu Hydropower Station and analyzes its formation mechanism with considering the effect of sudden drawdown, torrential rain and earthquake on stability of subgrade slope. The stability of cutting slope and high embankment slope along this section is analyzed with STAB2009 program and the design scheme and engineering measures on the slope are proposed. The reinforcement measures are effective and the subgrade slope stays stable.
