中文摘要：

基于求解稳定渗流场与弹性位移场耦合问题的全耦合分析方法,应用提出的混合遗传算法作为优化算法,同时利用水头、位移等多类型量测资料,提出了裂隙岩体渗流与应力静态全耦合的参数反演方法。在目标函数建立中考虑了实测水头对渗流参数的敏感性,在待反演力学未知参数的选取中,依据提出的相对灵敏度概念,考虑了实测位移对力学参数的敏感性。针对某裂隙岸坡算例,研究了水库蓄水过程中位移场对力学参数敏感性,据此实现位移测点的优化布置,并以渗流场与位移场全耦合正分析计算结果作为假想实测值,进行该岩坡的全耦合参数反演分析,从而验证了所提出理论与研制程序的正确性和可行性。

英文摘要：

A parameter inversion method is presented for fully coupled analysis of steady water flow and stress in fissured rock masses based on forward coupling analysis and new hybrid genetic optimization algorithms,as well as different types in-situ measured data of both water head and displacement.The sensitivity of in-situ water head measured data to seepage parameters is considered in constructing the objective function and the sensitivity of in-situ displacement measured data to mechanical parameters is conside...
