摘要

结合高填石路堤工后沉降变形机理与工程特点，基于工程实测数据，提出了高填石路堤工后沉降蠕变变形的双曲线型三参数本构模型，并引进遗传算法与有限元分析理论，建立了该模型参数的反演分析方法。在此基础上，利用蠕变有限元分析手段，深入探讨了高填石路堤工后沉降的分析计算方法，并开发了相应的分析计算软件。结合某高填石路堤工程实践，探讨了高填石路堤双曲线三参数蠕变本构模型和高填石路堤工后沉降计算的应用方法。工程实例分析表明，提出的本构模型及其工后沉降计算方法简单，可以满足工程要求，初步建立了一种新的高填石路堤工后沉降计算方法。

Abstract

Based on practical measuring data in engineering

the hyperbola-shaped constitutive model which has three parameters and reflects the law of creep deformation after construction for high rockfill embankment is firstly proposed by combing the mechanism of settlement with the features of engineering; and the back-analysis way that the model’s parameters are determined has been brought forward with introduction of genetic algorithm and finite element method. Afterwards，the computational means of the settlement after construction for high rockfill embankment is deeply discussed using finite element method for creep; and the relevant analytic software is developed. Finally

the application for the constitutive model proposed in this paper and the computational method of the settlement for high rockfill embankment is deeply probed by combining with the practices of engineering. It is indicated by analysis of the example of practical engineering that both the constitutive model for creep deformation and the computational means of settlement after construction are simple and reach the request of engineering practice

and a new computational method for the after-construction settlement of high rockfill embankment which is elementarily established
