【摘要】 对深溪沟水电站近坝区的黄草坪座落体的变形特征、成因进行分析,通过勘探平洞进行了地震波测试,对座落体压剪破碎带作了强度大剪试验,并结合现场查勘和数值计算对座落体的稳定性进行了综合评价。评价结果表明:该座落体整体处于稳定状态,不排除局部零星垮塌,以及浅表部位松散覆盖层蓄水后出现的微小垮塌情况,但不影响水库及电站的正常运行。更多还原

【Abstract】 We analyze the deformation features and formation causes of Huangcaoping sliding-falling body near the dam site of Shenxigou Hydropower Station,and conduct comprehensive evaluation on its stability by in-situ surveying and numerical calculations.The results show that the sliding-falling body is in stable state now in general;some scattered fallings may happen and the loose coverings may collapse after impoundment,but does not influence the normal operation of the hydropower station.更多还原
