摘　　要：文章根据工程的水文特点、自然条件、地质地形条件、当地材料等,结合导流方式和工程要求,施工期大坝围堰不仅承担施工导流挡水任务,同时还要满足工程施工期度汛100年重现期洪水的挡水要求。并简要介绍了大坝施工导流土石围堰的标准选择、断面形式和基础处理设计,为类似水电工程的施工导流围堰设计提供一定的实践经验和借鉴。Based on the project hydrology characteristics,natural condition,geological and topographical conditions,the local materials,and so on,combining with the diversion mode and the project requirement,the cofferdam in dam construction period not only undertakes construction diversion and water retaining task,but also meets water retaining requirement when one percent frequency flood happens in project construction.The paper introduces briefly the standard selection,cross section and foundation treatment design of the diversion earth-rock cofferdam in dam construction,which has reference for the similar projects.
