摘要：

Reasonable parameters are the premise of correct analysis of dam. The method of mechanical parameter determination is studied based on seismic response of dam using back-analysis theory. Firstly, a displacement statistical model under seismic load response is built, and a modified objective function is deduced. Then, finite element model of a built dam and genetic algorithm based calculation program are developed. Finally, the mechanical parameters of the system are inversed, optimized and verified. The results show that the inversed parameters are reasonably accurate, and the inversion method based on seismic response of dam is reasonable and feasible, which may provide significant reference for analyzing the behavior of dam.
