基于饱和多孔介质理论,根据一维饱和土动力响应问题的控制方程,以位移响应的理论合成与实际测量数据相拟合的原则,把饱和多孔介质的参数反演问题归结为非线性多峰函数的优化问题,研究了遗传算法和模拟退火算法在材料参数反演中的作用。通过数值算例表明了两种算法的正确性和可行性。
基于飽和多孔介質理論,根據一維飽和土動力響應問題的控製方程,以位移響應的理論閤成與實際測量數據相擬閤的原則,把飽和多孔介質的參數反縯問題歸結為非線性多峰函數的優化問題,研究瞭遺傳算法和模擬退火算法在材料參數反縯中的作用。通過數值算例錶明瞭兩種算法的正確性和可行性。

Based on the governing equations of dynamic response analysis for one-dimensioned saturated soil, according to principle that the computed response and measured response should be fitted, then the parameter inversion problem of porous media is reduced to optimal problem of non-linear multimode function, the role of genetic algorithm and simulated annealing in the inversion of material parameters is studied. The numerical results confirm that the genetic algorithm and simulated annealing are feasible and robust.
