| 摘 要： | 观音岩水电站位于金沙江上游,坝型初拟混凝土重力坝和心墙堆石坝组合坝.坝址区分布有侏罗系中蛇店组(J2s)地层,岩性主要为钙质铁质胶结的砾岩、石英砂岩,其中砾石成分以泥晶灰岩和生物灰岩为主.在地下水作用下砾岩钙质溶蚀形成规模较大的囊状空腔或孔洞,砂岩则表现为钙质胶结物流失溶蚀呈砂土状或砂糖状,对坝基稳定性造成了一定的影响...

| Abstract: | The Guanyinyan Hydropower Station locates in the upper reaches of Jinsha River.The dam type is a combination of concrete gravity dam and core rockfill dam.The stratum in the dam site is middle Shedian group of Jurassic.The lithology is mainly the calcareous ferruginous cemented conglomerate and the quartz sandstone.The main components of conglomerate are cryptite and biolithite.The large cystic cavities or holes are formed by corroded calcareous ferruginous under groundwater.The corroded calcareous cement i... |
