摘要
柬埔寨Atay水电站工程坝址两岸相对平缓、覆盖层深厚,为避免大开挖并减少混凝土工程量,设计采用两岸接头堆石坝+河床重力坝的布置形式,从而节约投资。介绍了复合土工膜心墙堆石坝的设计与施工方法,工程经过近4年的正常运行检验,证明复合土工膜心墙堆石坝的防渗效果是好的,防渗心墙与混凝土坝的连接设计是可靠的。
Atay Hydropower Project of Cambodia is located at a dam site with relative fiat terrain and thick overbur- den layer on both banks. In order to reduce excavation and concreting quantities as well as cost, roekfill dam seg- ments are designed at both banks and gravity dam segment designed on river bed. An instruction was made on the design and construction method of composite geomembrane core wall rockfill dam. The project has been put into op- eration for nearly four years, showing the anti-seepage of rockfill dam is good, and connection between impervious core wall and concrete dam is reliable.
