【摘要】 对土体本构模型的分类、建模理论及其研究方法进行了系统总结和分析,指出土体微细结构、状态参数、受荷历史、应力路径和排水条件等都可能影响土体本构模型的建立及其参数的确定。由于土体本构模型的复杂性,采用先进的自动化与自适应技术建立土体本构模型或对模型参数进行反演具有十分重要的意义,为此在分析本构模型的基础上,对本构模型中应用的自动化技术,包括神经网络、数据库和基于现场实测资料的反演等技术进行了探讨。更多还原

【Abstract】 By systematic summarization and analysis about classification,model construction theory and its research methods of soil constitutive model,it shows that soil microstructure,situation parameters,loading history,stress path and drainage condition all can in?uence soil constitutive model construction and determination of its parameters. Because of the model’s complexity,it has a very important significance in inversion of the model or model parameters by using advanced automation technologies and adaptive technologies. Therefore,on the basis of analyzing the model,the paper discusses automation technologies,such as neural network technology,database technology,and inversion technology based on measured data.更多还原
