摘　　要：委内瑞拉托科玛水电站溢洪道左岸边坡长约500m,位于委内瑞拉卡罗尼河下游,设计工程中将溢洪道边坡从上游向下游划分为Ⅰ~Ⅳ四个区域。在右岸边坡开挖施工中发现,Ⅱ区实际覆盖层厚度大于前期的预判,文章主要对溢洪道边坡Ⅱ区未采取支护措施情况下开挖边坡进行稳定计算,并根据计算成果确定支护方案,从而对支护后的边坡稳定开展计算,最终确定锚索间距及锚固长度。The left bank slope of the spillway in Venezuela Tocoma Hydropower Station is about 500m long.It is located in the lower reaches of Venezuela Caroni River.The spillway slope is divided into four zones ofⅠ~Ⅳfrom the upstream to the downstream in the design project.It is found in the right bank slope excavation that the actual overburden thickness of zoneⅡis greater than the previous prediction.The excavation slope stability is calculated in the paper mainly under the condition that the spillway slopeⅡarea is not provided with supporting measures.The support scheme is determined according to calculation results.The slope stability after supporting is calculated,thereby ultimately determining the anchor cable spacing and anchor length.
