摘　　要：茶林寨水库经过多年的运行,坝体和坝基严重渗漏,需对其进行防渗加固处理。分析了大坝防渗加固的常用措施,基于当地实际工程地质情况,初步选择了可控复合膏浆灌浆+帷幕灌浆、高压喷射灌浆+帷幕灌浆、黏土固化剂灌浆+帷幕灌浆3种防渗加固方案。从技术、经济方面,对这3种方案进行比较,确定坝体采用可控复合膏浆灌浆,坝基采用帷幕灌浆的防渗加固方案。探讨了该方案的具体实施步骤和关键技术问题。The Chalinzhai reservoir has been in operation for many years,and the dam body and foundation have suffered serious seepage.Therefore,it is necessary to carry out anti-seepage reinforcement treatment.The common measures for dam anti-seepage reinforcement were analyzed,and based on the actual engineering geological conditions in the local area,three anti-seepage reinforcement schemes were initially selected:the controllable composite paste grouting and curtain grouting,the high-pressure jet grouting and curtain grouting,and clay solidification agent grouting and curtain grouting.From the technical and economic aspects,the three schemes were compared,and the dam body was determined to adopt controllable composite paste grouting,and the dam foundation was to adopt the curtain grouting for anti-seepage reinforcement scheme.The specific implementation steps and key technical issues of the scheme were discussed.
