Analysis on the measured settlement and prediction modeling of statistic settlement of Shuibuya CFRD

WANG Pengxu,SONG Wenjing (State Key Laboratory of Hydroscience and Engineering,Tsinghua University,Beijing 100084)  
The settlement data measured in situ of the Shuibuya concrete faced rock-fill dam are analyzed,and a coupled prediction model of exponential statistic settlement is proposed.The monitoring instruments of this dam work in good order,and the measured settlement contours show reasonable trends.The maximum settlement is about 1% of the height of constructed rock-fill dam,and the average of the computed vertical compression modulus is above 100MPa,which indicates a satisfactory compaction quality.The proposed prediction model takes into consideration the influencing factors such as gravity weight,water pressure and rheological properties of rock-fill materials.The predicted maximum settlement of the rock-fill dam will be about 2.46m in 5 years after the dam completion.
