Because of the complexity and variety of geotechnical material
the rheology constitutive models put forward by existing FEM software can’t usually satisfy the requirement of actual numerical analysis. In accordance with fundamental code-run-principle of FLAC3D Version 2.1 software
the basic principle of the secondary development program running is made
and detailed analysis combined with the Nishihara viscoelasto-plastic rheological model is given. The program flow diagram on the special execution of Nishihara rheological model and several case technique that should be taken into account in the process of code compiling is given. At the same time
an easy case is used to verify the right and credibility of program compiling. The Secondary development environment is more friendly and effective with the support of object-oriented approach. Therefore
proposed design mode can bring forward references for the secondary development of other rheological models.
