摘　　要：随着水利水电工程中采用越来越多的超深(大于100m)混凝土防渗墙进行坝基防渗处理,现行行业规范和定额已远不能满足超深混凝土防渗墙投资编制的需求。本文在现行水电建筑工程概算定额(2007年版)基础上,结合本文作者相关研究成果,提出了超深混凝土防渗墙成槽单价编制要点,并通过四川省狮子坪水电站大坝隐患治理新建混凝土防渗墙成槽单价编制过程进行实例分析,可为水利水电工程超深混凝土防渗墙投资编制提供参考。With the increasing use of ultra-deep(greater than 100 meters)concrete cutoff walls for dam foundation seepage control in water conservancy and hydropower projects,the current industry standards and norms are no longer sufficient to meet the needs of investment preparation for such structures.Based on the current Hydropower Construction Budget Quotas(2007 edition)and the authors’related research findings,this paper proposes key points for preparing the unit price of slotting for ultra-deep concrete cutoff walls.Additionally,it presents a case study of the unit price preparation process for the new concrete cutoff wall constructed as part of the hazard remediation for the Shiziping Hydropower Station Dam in Sichuan Province.This study can serve as a reference for investment preparation in water conservancy and hydropower projects involving ultra-deep concrete cutoff walls.
