【摘要】 基于进化理论的全局优化算法为岩土工程优化反分析提供了一种解决实际问题的思路,但计算效率不高是这类算法的最大问题。为了克服这类算法的缺点,提高反分析的计算效率,引入了免疫克隆算法,并将免疫克隆算法应用到大坝坝体混凝土弹模反演分析中去。工程实例计算结果表明:免疫克隆算法不仅参数设置简单,而且有着较高的收敛速度和计算精度,值得进一步研究、推广和应用。更多还原

【Abstract】 The global optimization algorithms based on evolutionary theory provide a methodology for optimization and inverse analysis of geotechnical engineering. But the efficiency of these algorithms is low. In order to overcome the disadvantage of these algorithms, immune clonal algorithm is proposed and applied in the inverse analysis of dam concrete elastic modulus. The result shows that immune clonal algorithm is simple in parameters’ setting with speedy convergence and high accuracy, and is worthy of further study, extension and application.更多还原
