摘　　要：对某工程大坝趾板施工过程中遇到的技术难题进行实证分析,并对比两种技术方案的优势与不足,认为帷幕灌浆与防渗墙方案技术可行、风险可控。最终的权威检测表明:大坝趾板基面固结灌浆、帷幕灌浆后,波速均达到设计相关要求,取得了理想的效果,达到了施工质量预期。This paper analyses the difficulties occurred during construction of toe plate area of the lower reservoir dam of a pumped storage power station.By contrastive analysis of treatment schemes,the con⁃clusion is obtained that the adoption of curtain grouting and impervious wall is technically feasible and risk controllable.Then the curtain grouting and consolidation grouting are carried out,which are effective.

关 键 词：大坝趾板 帷幕灌浆 防渗墙 施工方案
