四川鸭嘴坝址右岸滑坡对坝址选择影响的分析

Analysis on the impacts of Sichuan duckbill dam site right bank slope on dam site selection

对四川凉山州鸭嘴河拟建鸭嘴坝址进行地质勘察之后,证实坝址右岸存在一个较大的基岩滑坡,预计在设计水库水位时,滑坡体将产生滑塌成为右岸的不稳定因素,从而使右坝肩存在稳定和渗漏等严重工程地质问题,故建议放弃鸭嘴坝址。

After geological survey on proposed constructing duckbill dam site in Liangshan duckbill river in Sichuan,it proves that right bank of the dam site exists a big foundation rock slope.It predicts that the landslide will produce collapse,which will become unstable factors of the right bank.Furthermore,it will lead to serious stable and leakage engineering geological problems for the right dam.Therefore,it suggests quitting the duckbill dam site.
