巴基斯坦国阿莱瓦水电站厂房后边坡较为高陡,地质条件较差,且处在地震多发区,施工期边坡上出现大的裂缝并不断扩展。边坡的稳定性直接影响着水电站厂房的安全运行。文章分析了边坡顶部的裂缝成因及发展规律,通过国际通用软件SLOPE/W分析了厂房后边坡在正常施工期、正常运行期、强降雨及地震等工况下的稳定性,并提出了厂房后边坡的预应力锚索加固处理措施。 The slope behind the Alawewa hydropower plant in Pakistan is relatively steep with poor geological conditions and is located in an area prone to earthquakes. Large cracks on the slopes during the construction period have been continuously expanding. The slope stability directly affects the safe operation of hydropower plant. This paper analyzes the causes and development of cracks at the top of slope and analyzes the stability of slope after the plant under normal construction period, normal operation period, strong rainfall and earthquake through the international common software SLOPE / W, Rear slope of the prestressed anchor reinforcement measures.
