摘　　要：在分析当前围堰防渗工程的块石架空层和高水头、大流量水力条件下的灌浆施工难点,对灌浆浆液的性能要求及相关水下不分散外加剂的发展和国内外研究现状的基础上,对水下不分散浆液的原材料进行了对比分析,并根据灌浆的性能要求和标准进行室内试验,配制了具有抗水流冲释能力的新型灌浆浆液,满足工程实际需要。The grouting difficulties in large rock cavities layers or the situations under high water head and large flow on construction of cofferdam seepage prevention are analyzed, and the requirements on the performances of grout,the development and recent research situations of the related non-dispersive underwater admixture at home and abroad are investigated. On the basis of this,the raw materials for the non-dispersive underwater grout are compared, and laboratory tests are made based on the performance requirements of the grout and the national regulations. Finally,a new type of grout,which have the property of antiwashout,is prepared to meet the actual demand of the project.
