摘要
针对目前获得基床系数的方法存在诸多缺陷,且给出的经验值范围较为宽泛,取值存在一定困难.本文提出了一种新方法,根据非线性模型参数遗传算法估计原理,依据基础沉降数据,结合弹性地基梁有限元方法对基床系数进行反演分析.通过算例的检验,证明本文所提出的反演方法是正确和可行的,再将该方法用到实际的工程中,得出的结果也较目前应用的基床系数更能反映实际情况.
Nowadays,there are some demerits existing in methods to obtain coefficient of foudation.The range of empirical value provided by these methods is too wide,so that to get the true value is a little bit difficult.In order to solve the above problems,this thesis comes up with a new method.According to the principle of non-liner parameters evolution of genetic algorithm and based on the settlement datum of foudation,inversion analysis of coefficient of foundation can be carried out,combining with the FEM method of the elastic foundation beam. Through examples＇examination, it can prove that the inversion method proposed by this thesis is correct and feasible. Applying this method to practical project, the coining results can also better reflect the actual situation than coefficient of foundation currently used.
