摘要
采用邓肯-张非线性模型描述填石体的力学特性,引入遗传算法和有限元分析,建立了填石体本构模型参数的进化反演方法。最后结合某高填石路堤施工期实测沉降数据进行参数反演,并利用反演参数对类似断面进行了施工期沉降预测。结果表明,利用反演参数计算得到的施工期沉降值与实测值较为吻合,为制定合理的路堤填筑计划提供了依据。
<Abstrcat> In this paper, based on Duncan-Chang nonlinear elastic model, the Genetic Algorithm and FEM are adopted to construct back analysis method of model parameters. The settlement monitored in site was analyzed by the method, and the parameters obtained were used to calculate the settlement during construction in another section. The result fit the monitored data very well,and it will be helpful for decision making during highway embankment construction.
