摘　　要：喜儿沟水电站位于甘肃省舟曲县境内的白龙江干流上游,电站坝址距兰州市公路里程403 km,距舟曲县城34 km。5^(#)渣场位于喜儿沟水电站厂房下游约80 m的白龙江右岸斜坡上,坡脚有S313省道通过。该渣场原设计堆渣量21万m^(3),目前堆渣约34万m3。该渣场坡体的稳定与否,将直接影响到S313省道的安全,因此,对现有渣场边坡、挡渣墙及其基础进行稳定性计算分析论证、提出合理的处理方案是非常必要的。研究该渣场的基本特征,选用合理的计算模型与力学参数对其稳定性进行计算分析,并在此基础上提出相关处理措施建议。The Xiergou Hydropower Station is located on the upper reaches of the main stream of the Bailongjiang River in Zhouqu County,Gansu Province.The dam site is 403 km away from Lanzhou City and 34 km from Zhouqu County town by road.No.5 spoil disposal site is situated on the right bank slope of the Bailongjiang River,about 80 meters downstream of the Xiergou Hydropower Station powerhouse,with the S313 provincial road passing through the foot of the slope.Originally designed for a spoil volume of 210,000 m,the site currently holds approximately 340,000 m of spoil.The stability of this slope directly affects the safety of the S313 provincial road.Therefore,it is essential to conduct stability calculations and analyses for the existing spoil disposal site slope,spoil retaining wall,and its foundation,and to propose reasonable treatment solutions.This study examines the basic characteristics of the spoil disposal site,selects appropriate calculation models and mechanical parameters to analyze its stability,and provides relevant recommendations for treatment measures.
