| 摘 要： | 基于ABAQUS软件提供的二次开发平台，开发了土体分级单屈服面弹塑性本构模型的子程序，并完成了2个典型的算例。计算结果与Desai计算结果及模型试验实测结果进行了对比，检验了模型的正确性。给出了在ABAQUS中开发弹塑性本构模型的基本步骤和编程要点，可为其他用户进行本构模型的修改提供借鉴与参考。模型的成功开发可为建筑结构的地基基础有限元分析提供一种适用的本构模型

| Abstract: | The basic features of finite element software ABAQUS are introduced briefly; and the hierarchical single surface(HISS) model was developed based on the further development platform provided by the software; and two numerical examples were also solved. The correction was verified through comparing the calculation results of ABAQUS with the results computed by Desai and the test data of model test. The basic procedures and programming essentials are presented, so as to provide reference to other developers. Meanwhile, the implementation of HISS model in ABAQUS can provide an optional constitutive model for finite element analysis of foundation of building structures in soft soil. |
