摘　　要：紫坪铺工程面板坝坝体变形和沉降控制与#1、#2泄洪洞高速水流控制设计是本工程突出的两个关键技术问题,面板堆石坝设计中成功采用表面振动器法测试最大干密度,以压实度确定坝料填筑标准的方法;#1、#2泄洪洞创新地采用了簸箕状挑坎和缓坡段环形掺气挑坎,成功解决了46m/s的超高水流速问题。Both dam body deformation and settlement control with design of high velocity flow control for #1 and #2 discharge tunnels are the two prominent technical issues for Zipingpu project.The surface-type vibrator method is used to measure maximum dry density and also the compaction degree is used to determine dam material filling standard in the design of concrete-faced rockfill dam.Dust-pan shaped bucket and annular bucket aerator at gentle-slope section are adopted for #1and #2 discharge tunnels as innovative approaches,which successfully solve 46m/s hyper velocity flow problem.
