旁多水利枢纽工程拦河坝设计

Dam design for Pangduo hydro-junction project

文章介绍了拉萨河上旁多大坝坝型选择,得出碾压式沥青混凝土心墙砂砾石坝方案投资最低,比碾压式沥青混凝土心墙堆石坝方案和粘土心墙砂砾石坝方案减少投资9.3%和2.5%。最终选定碾压式沥青混凝土心墙砂砾石坝方案。文中还介绍了该坝的护坡型式、坝体结构设计及基础防渗处理。

Based on the dam type selection for Pangduo project in Lasahe river,the paper describes the scheme investment of the roller compacted asphalt concrete core wall sandy gravel dam is the lowest,which could reduce 9.3% compared with the roller compacted asphalt concrete core wall rockfill dam scheme and reduce 2.5% compared with the clay core wall sandy gravel dam.Then the dam type scheme of the roller compacted asphalt concrete core wall sandy gravel dam is determined.The paper also introduces the type of dam slope protection,the dam structural design and the foundation impermeability treatment.
