Abstract: Monitoring items for spillway which is also used as diversion tunnel in reconstruction of Fengman dam are introduced. In order to study the change of seepage pressure of spillway, the reliability of monitoring data is checked firstly, then the time- space distribution curve is drawn and the statistical model is established. By qualitative and quantitative analysis of seepage pressure, it is concluded that the seepage pressure of spillway is basically stable.

Key words: reconstruction of Fengman dam, spillway as diversion tunnel, seepage pressure, monitoring data analysis

摘要： 对丰满大坝重建工程泄洪兼导流洞监测项目进行了介绍。为判断泄洪兼导流洞渗透压力的变化情况，首先对监测数据进行可靠性检查，然后绘制时空分布曲线和建立统计模型，对渗透压力物理量进行定性和定量分析，得出泄洪兼导流洞渗透压力基本稳定的结论。
