7、城92Km；右岸属甘肃省***县**镇，距***县城29Km。对外有青海省川官（**-官亭）公路，交通方便。该电站以发电为主。设计正常蓄水位1783m，与积石峡水电站尾水衔接,坝顶高程1785m，最大坝高上坝址15m、下坝址46m,装机容量上坝址（引水方案）220MW、下坝址（河床式厂房）140MW,总库容上坝址约367万m3、下坝址约560万m3，工程属中型三等工程，主坝坝型为砂砾石堆石坝，副坝坝型为均质土坝。枢纽主要建筑物为三级，由拦河大坝、发电引水渠（上坝址）、厂房、泄水闸、开关站等建筑物组成，199

8、0年4月底对该枢纽进行了规划选点踏勘工作，1991年5月底陆续开始地勘工作，同年11月提交《黄河龙羊峡—刘家峡河段中型电站规划阶段**水电站工程地质报告》。2001年4月中旬，我院中标**水电站预可行性研究阶段的勘测设计工作，5月中旬专业人员进行现场踏勘，拟选上、下两个坝址进行预可行性研究阶段的工作，于10月底完成本阶段的全部勘测工作。2002年2月规划院专家组对预可研报告初稿进行了咨询，并提出咨询意见。主要勘测
