格里桥水电站厂房上游侧边坡坡脚水毁修复处理工程技术文件1.工程剖析
1.1工程说明
格里桥水电站位于贵州省贵阳市开阳县与黔南州瓮安县交界的清水河干流上。
其下游接构皮滩水电站，距清水河出口约44km，上游接大花水电站梯级，距大花水电站厂房区约19.5km，装机容量2×75MW，距贵阳约108km。
格里桥厂房上游侧边坡坡脚受2015年7月16日泄洪冲刷影响，导致厂房上游侧658m高程至河床边坡被冲刷破坏，为保证上游边坡及出线塔架基础的稳定。
拟采用钢筋混凝土护坡对已冲刷损毁的边坡进行修复处理。
1.2工程地质
格里桥厂房上游侧边坡基岩为逆向坡，地层岩性为为吴家坪（P2w3）薄层至厚层硅质岩与页岩、炭质页岩互层夹燧石灰岩，局部夹层厚度达0.15~1.8m，边坡岩体为弱风化岩体及微新岩体，岩溶不发育，受风化及裂隙的影响，岩体较为破碎。
排水洞出口至厂房尾水渠上游导墙部分边坡为覆盖层及石碴回填边坡，坡内有大孤石及零星基岩出露，覆盖层深槽部位有钢筋混凝土灌注桩承台基础。
河床水位约为619m~627m，河床内有泄洪后两岸垮塌的碴料及大块石。
1.3水文气象
清水河流域属于亚热带季风气候区，夏季受太平洋副热带高亚控制和西南海洋性暖湿气流影响，冬季主要受西风北支急流的影响，气温和降水四季变化明显，冬季气温低而干燥少雨，夏季气温高而湿润多雨。
本流域多年平均降水量在1000m~1350mm之间，年内分配极不均匀，4~10月占全年降水量的86.5%，而12月、1月、2月降水量只占5.4%。
格里桥坝址5月~9月平均气温超过20.0℃，年内7月气温最高，1月最低，最高气温39.3℃，最低气温-6.2℃。
