Abstract The water leakage of existing tunnel lining occurred frequently after its operation. During construction of tunnel, the water proofing and drainage techniques should be taken into special attention, so as to construct tunnel without leakage, which is the main requirement to guarantee the safety running of the trains and the long duration of the tunnels. The cause of the formation of water leakage in tunnel lining are analyzed, and the corresponding measures for preventing water leakage and gushing water in tunnel are proposed.
