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.
