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 supply in the new area, with high requirements for project seepage prevention. The F173 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 reservoir 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 reservoir. In order to explore a suitable implementation method for curtain grouting of Xiongan storage reservoir, it is necessary to determine the anti-seepage treatment measures, grouting construction method and construction technology of the F173 fault through grouting test research. The results indicate that the permeability meets the anti-seepage standards and the fatigue resistance is improved.
