| 摘 要： | KLSK水利枢纽采用河床布置碾压混凝土重力坝及右岸布置引水发电系统的格局。上下游围堰处河床覆盖层厚达13m左右，受多年人工采金影响，已被严重扰动、分选，基础具有强透水性。采用槽孔防渗墙，结合灌浆加固槽孔、旋挖成墙的施工工艺，较好地解决了围堰基础处理上的难题。

| Abstract: | KLSK Hydraulic Complex is designed with RCC gravity dam on fiver bed and diversion power generation system by the fight bank. The 13m-thick overburden layers at the positions of upstream and downstream cofferdams had been seriously disturbed and separated due to many years of manual gold mining. In view of the strong permeability of foundation, slotted anti-seepage wall design was adopted, combined with the construction technique of slot reinforcement by grouting and wall forming by rotary dredgingx, rendering relatively good effeet. |
