Abstract
Appropriate layer quantity has been considered to model the sequential construction of a high embankment dam over 300 m and its effect on the predicted settlement of the 314 m high Shuangjiangkou dam has been discussed. The simulation results have demonstrated that at least 25 layers are required to accurately model the stage construction of a high embankment dam over 300 m. The stress and deformation within the dam and the foundation during the dam construction and reservoir filling have been simulated using finite element analysis. Saturated-unsaturated seepage theory is used to analyse the transient seepage field in the dam and in the foundation. Two different cases about the construction and the operation are modelled. One involves gradual reservoir filling after the completion of sequential construction, whereas the other involves sequential construction and reservoir impounding by several interleaved stages. The simulation results for both cases have been compared and discussed.
