绩溪抽水蓄能电站下库大坝分期分区填筑施工工艺

摘要

根据绩溪抽水蓄能电站下库大坝各种填筑料工程量及填筑强度,进了分期、分区填筑施工规划,针对上下游堆石料、过渡料、垫层料、特殊垫层料分别选择了适当的施工工艺.最终下库大坝填筑施工效果较好,坝体填筑均衡上升,保证了大坝填筑均匀沉降,满足了设计质量要求.%According to the filling quantity and intensity of various filling materials for the lower reservoir dam of Jixi Pumpedstorage Power Station,the staging and zoning filling is planned,and appropriate construction technologies for the construction of rockfill materials,transition materials,cushion layer materials and special cushion layer materials are also selected respectively.The actual construction shows that the filling construction of lower reservoir dam is well,the dam body filling is balanced raised and the dam body settlement is uniform,which meets designed quality requirements.
