摘　　要：结合工程实际,重点对如何运用周边缝的设置,采用浆砌石挡墙挡坝体,避免高趾墙的混凝土浇筑对坝体上升的影响;采用混凝土挤压边墙等先进技术,加快施工进度;对大坝基础防渗处理上采用分部位分高程设计等方面进行了详细论述,以供同类工程交流借鉴。With the combination of practical engineering, the questions about how to use peripheral joint, adopting block masonry retaining walls were mainly discussed to avoid the effect of the concrete placement of high-toe wall to the rising of dam body. Advanced techniques of concrete extrusion side wall were adopted to speed up construction progress. Dam foundation anti-seepage was designed as treating by different positions and different elevations, which provides ref- erence for similar project.
