【Abstract】 In this paper, a hybrid model is presented based on the observation data collected during the construction period of a large dam. The Xiongdu Arch Dam in Hubei province is analyzed by means of the three dimensional finite element method, considering the effects of such factors as water pressure, temperature, time effect, constructed height, grouting stage, and cement hydration heat in the construction period. The results from the model provide a reasonable basis for the explanation and evaluation of the behavior of the large dam and for the realization of the monitoring of dam safety.更多还原
