| 摘 要： | 由于岩土介质的复杂多样性，通用分析软件所提供的岩石流变本构模型往往不能满足工程实际数值分析的需要。依据FLAC^3D（Vcrsion2．1）所提供的二次开发程序接口，结合西原黏弹塑性流变模型分析了二次开发程序运行的基本原理，给出了西原流变模型具体实施的程序框图和代码编写中应该注意的几个关键技术。通过一个简单的算例验证了程序编制的正确性与可靠性。由于采用了面向对象的程序技术，FLAC^3D二次开发接口更加简单实用，提供的研究思路可为其他流变本构模型的二次开发提供参考。

| Abstract: | 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. |
