摘　　要：分析了三峡蓄水至172 m永久船闸的渗压情况。渗压是影响永久船闸安全运行的重要因素,为监测其渗压情况,设置了完整的渗流渗压监测系统。对船闸运行长期以来及三峡水库蓄水加密观测资料进行了统计分析并对典型测点建立回归方程,以了解建筑物基础渗压变化规律及变化趋势,为其安全运行提供了依据。The seepage-pressure of Three Gorges Project＇s shiplock area during the first storage to 172m is analyzed.The seepage-pressure is an important factor that affects the safe operation of the Three Gorges Project＇s shiplock area and a complete monitoring system is set up to monitor the seepage pressure situation.In this paper,the data from long-term observations and encryption observation in the storage period are analyzed statistically,and a regression equation for typical measuring points is established.The equation can help us to understand the changing law and the changing trends of the seepage pressure of the building foundation,and it provided a grarantee for the safe operation.
