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
