Abstract: In October 2004, leakage was found in sluice gates of Zhaoshandu water diversion project. At the beginning of 2008, the leakage had developed into flow jet. It’s clear that the leakage problem was getting worse. This paper introduces the seepage control system and the development process of leakage. The safety conditions were checked by calculation, the hidden defects of seepage stability were pointed out and the safety status was comprehensively analyzed. At the same time, the specific measures for the anti-seepage treatment were introduced, for reference.
