改进复合形法及其在堆石坝参数反演中的应用
Modified complex method and application to parameters back-analysis for rock-fill dam
摘要
Abstract
A modified complex method based on chaos optimization is put forward to overcome the limitations of basic complex method,weak global searching capability and high probability of mapping failure for complicated optimization problems.It uses the features of chaos such as inherent randomness,ergodicity and sensibility to initial condition and takes the measures of constructing an initial complex by introducing chaotic variables,generating initial mapping parameters by using chaotic sequence and handling mapping failure by adding chaotic variables to disturb the current state of the complex.An algorithm is worked out and applied to parameters back-analysis of the Yele asphalt concrete core rock-fill dam.The results of this method show improvements in stability and convergence rate.关键词
