巴基斯坦卡洛特水电站沥青混凝土心墙堆石坝反滤料设计

Filter design of asphalt concrete core rockfill dam of Karot Hydropower Station in Pakistan

软岩填筑堆石坝的坝壳料细颗粒含量多,通常需要进行反滤保护。以卡洛特水电站沥青混凝土心墙堆石坝反滤料设计为例,详细介绍了软岩填筑堆石坝反滤料设计原理、设计过程和设计步骤,并通过反滤试验验证了设计成果的合理性。该反滤料设计能够有效保护软岩堆石料细颗料,可为其他软岩填筑堆石坝工程反滤设计提供参考。

There are large fine particle content in those dam shells of rockfill dams built with soft rocks,so it is nec⁃essary to set filter to protect dam shell rockfill material.Taking the design of the filter for Karot asphalt concrete core rockfill dam as an example,this paper describes the design theory,process and steps of the filter for soft rock rockfill dam in details,and the designed results are verified by filter test.This design of filter can protect the dam shell rockfill material effectively and provide a reference for other similar soft rockfill dam projects.
