摘要: 改进了进化方向的遗传算法与有限元数值法, 结合并研制了相应的软件.应用该软件对多类型岩土边坡进行弹性模量、内聚力、内摩擦角等参数反演分析, 显示误差很小, 收敛速度也很快, 这说明改进进化方向遗传算法这种新型的优化算法在多类型岩土参数优化估计中具有独特的优势.Abstract: The approved genetic algorithm was combined with finite element method in developing relevant software. The software was applied to make back analysis of elastic module, cohesion, friction angle for the slope with different soil types. The results show that the error is quite small and convergence rate fast. It is proved this algorithm is of obvious priority in rock soil parameter estimation.
