潘口水电站混凝土面板堆石坝坝体优化设计

Optimized design of dam body of concrete face rockfill dam of Pankou Hydropower Station

潘口水电站原料场由于料源不足以及石料质量不理想,需要进行变更。介绍了料源变更的理由和新料源的选择过程。根据实际情况,在不改变原设计剖面条件的情况下,修改了坝体填料分区,并对变更后的大坝混凝土面板堆石坝进行了安全监测。监测结果表明,枢纽工程基本处于稳定状态,面板堆石坝的坝体填筑材料分区设计是合理的。

The material field of Pankou Hydropower Station needed to be changed due to insufficient material sources and poor quality. The reasons for the change of material sources and the selection of new material sources are introduced. According to the engineering practice, the zoning of dam body filler was modified without changing the original designed profile. And after the changes, the safety monitoring was conducted to the concrete face rock fill dam. The results show that the project is in stable con- dition, and the zoning of dam body filler is reasonable.
