摘　　要：在三峡水库蓄到高水位156 m高程及运行过程中,对泄洪坝段的渗流进行了监测,监测结果表明,泄洪坝段的坝基(体)渗压、坝基扬压力和渗流量等测值较小,均在设计允许范围内,其分布及变化符合一般规律。三峡工程泄洪坝段实测渗流性态正常,为三峡工程的施工及运行安全提供了科学依据。During the process of operation and water storage to 156 meters high of Three Gorges Reservoir,the seepage through the spillway section is monitored.The analysis of the measured seepage data indicates that the seepage pressure is generally low,and the quantity of the seepage through dam and its foundation is small,so the measured values can meet the design requirement.The pressure and volume of the seepage are distributed in accordance with the general law.The property of the measured seepage through the spillway section of Three Gorges Project is normal,thus to provide some important scientific references for the safety in stage of construction and operation of Three Gorges Project.
