摘　　要：大化水电站扩建工程的接头土石坝中间设置刺墙坝,使得坝顶能够提前贯通,机组设备大件能够提前运输至厂房进行安装,缩短了发电工期,同时采用简洁的体型,减少刺墙坝对土石坝的施工干扰,并进行了基础处理。经过两年多时间的运行,证明刺墙坝设计合理、安全稳定,满足使用功能。The dam crest of Dahua hydropower station was linked in advance because of a thorn wall dam set in the middle of the joint earth-rock dam;therefore,the large equipments can be transported to the power house for installation,which greatly shortens the construction period.Meantime,a simple-shaped thorn wall dam is adopted so as to reduce its interference on earth-rock dam construction.After more than two years running,it is proved that the thorn wall dam is in reasonable and safe design with very good stablility,which meets the requirement of designed function.
