杨林隧道最大埋深450 m，全隧富含基岩裂隙水、构造裂隙水、局部岩溶水等地下水，大部分区段经地质勘测出水量为88．31 m3/d·m。隧道施工防排水难度大、危险性高，高水压对隧道运营威胁严重。通过施工过程的堵、排结合方式解决施工及后期运营安全，设计过程以实际为出发地点进行计算，避免了盲目选取参数和设备。

양림수도최대매심450 m，전수부함기암렬극수、구조렬극수、국부암용수등지하수，대부분구단경지질감측출수량위88．31 m3/d·m。수도시공방배수난도대、위험성고，고수압대수도운영위협엄중。통과시공과정적도、배결합방식해결시공급후기운영안전，설계과정이실제위출발지점진행계산，피면료맹목선취삼수화설비。
With the greatest burial depth of 450 m,Yanglin tunnel is rich in bedrock crevice water,structure crevice water along the entire tunnel,karst water in some parts,mostly with geological surveyed water discharge of 88.31 m3/d·m.The water prevention and draining is faced with great difficulty and risk and the high water pressure poses serious challenge to the tunnel operation.A combination of blocking and draining is used to ensure the construction and operation safety.The design process is based on the actual location to avoid the blind selection of parameters and equipment.
