摘　　要：雄安调蓄库为抽水蓄能水库,是支撑雄安新区建设发展的重要水源工程,以及保障新区供水安全的关键配套工程,对工程防渗要求较高。库盆范围最大的F173断层以NE-SW向贯穿,并在库盆NE侧、SW侧形成低矮的垭口,沿断层局部发育有溶蚀现象。水库岩性、构造封闭条件较差,为控制水库渗漏,库周采用帷幕灌浆防渗。为探索适合雄安调蓄库帷幕灌浆的实施方式,需要通过灌浆试验研究,确定针对F173断层的防渗处理措施、灌浆施工方法和施工工艺。结果表明,各部位岩体灌浆后透水率满足防渗标准要求,抗疲劳特性得以改善。The Xiongan storage reservoir is a pumped storage reservoir,an important water source project supporting the construction and development of the Xiongan new area,and a key supporting project to ensure the safety of water sup-ply in the new area,with high requirements for project seepage prevention.The F 173 fault,which is the largest fault in the reservoir basin,runs through the NE-SW direction,and forms low passes on the NE side and the SW side of the res-ervoir basin,and there is local dissolution along the fault.The lithology and structural sealing conditions of the reservoir are poor.In order to control the seepage of the reservoir,curtain grouting was used to prevent seepage around the reser-voir.In order to explore a suitable implementation method for curtain grouting of Xiongan storage reservoir,it is necessa-ry to determine the anti-seepage treatment measures,grouting construction method and construction technology of the F 173 fault through grouting test research.The results indicate that the permeability meets the anti-seepage standards and the fatigue resistance is improved.
