Abstract: In order verify the effect of the grout improvement and to ensure the operation safety of the Caitugou Dam of Shenmu County, Yulin City in Shaanxi Province, the automatic monitoring system was used to monitor the long term settlement at the spillway tunnel. The monitored data were also used to evaluate the stability of the dam foundation. Both the empirical creep model and the exponential creep model are used in fitting the observed dam settlement data. The results indicate that both models can provide satisfactory results for the settlement prediction.

Key words: Empirical Creep Model, Exponential Model, Dam Settlement Prediction
