Abstract: We have studied the leakage problem of underwater transverse joints in dam operation period, and then put forward the replacement grouting method to plug sealing check slots. This paper introduces the principle, construction condition and application process of the method. Moreover, this paper also describes the characteristics and application scope of this method, as well as its application in the Three Gorges dam, which proves that the method is effective for solving the seepage problem of dam transverse joints.
