摘　　要：新疆希尼尔水库为西北平原水库的典型代表,坝基地质情况较为复杂,防渗方案是主要技术问题,在进行方案比选时要结合工程实际情况,优先选用安全可靠、防渗效果好、投资少的防渗方案。分别从希尼尔坝基地质特性、施工可行性、经济比较等多个方面,分析研究该水库除险加固坝基防渗处理方案,通过对各方案的综合比较,最终采用CSM铣削深层搅拌防渗墙方案对希尼尔水库进行坝基防渗加固。加固后,墙体抗压强度、抗渗系数均满足设计要求,该方案可为类似工程除险加固提供借鉴。Shinil reservoir is a typical one on the plain of Northwestern China,with complex geological conditions at the base of the dam.To ensure the sound operation of the reservoir,consideration must be given to seepage control,and the solution must factor into the context in which the project is operated.Preferably,the solution is safe,reliable,effective and economical.This paper provides an analysis of the geological conditions of Shinil Reservior,and compares different seepage control solutions in terms of their feasibility and cost-effectiveness.Through a comprehensive comparison of various schemes,the CSM milling deep mixing cut-off wall scheme was finally used to strengthen the dam foundation of the Shinil Reservoir.After reinforcement,the compressive strength and seepage coefficient of the wall meet the design requirements.This scheme provides a reference for similar projects to remove dangers and strengthening.
