Abstract: The paper analyzes the seepage monitoring result of TGP five-grade ship lock & its high slope. Through the analysis,we think that the underground water level of high slope be mainly influenced by the ship lock chamber excavation and the rainfall.The underground water level is currently steady approximately;the underground water pressure of high slope and the seepage pressure behind chamber bottom plate and lock walls, are quite low and within the range of allowable design.?

摘要： 本文对双线五级船闸及其高边坡的渗流监测成果进行分析，通过分析认为高边坡地下水位主要受闸室开挖和降雨影响，目前地下水位基本稳定，高边坡地下水压力和闸室底板、闸墙背后渗压较小，均在设计允许范围内。
