溧阳抽水蓄能电站上水库面板堆石坝设计

Face Rockfill Dam Design of Upper Reservoir of Liyang Pumped-storage Power Station

溧阳抽水蓄能电站上水库主坝坝基地形条件复杂,不均匀变形问题突出。重点对钢筋混凝土面板堆石坝进行了研究与设计,通过对坝基地形的适度修挖并结合有限元理论计算分析,对大坝进行了综合研究与设计,选定了合适的大坝体形、材料分区及坝料填筑指标等,可满足大坝安全运行的要求。

The dam foundation of Liyang Pumped-storage Power Station upper reservoir has complex topography and outstanding uneven deformation. The reinforced-concrete face rockfill dam was mainly studied. In the design of dam, the dam shape, material zoning and filling materials parameters are selected after foundation excavation study and finite element analysis. The design can meet the requirements of dam safe operation.
