摘要

根据FLAC3D软件提供的二次开发平台，利用VC++环境在FLAC3D软件中实现了邓肯-张本构模型的开发，设计了一系列三轴试验的模拟算例对模型开发的正确性进行了验证。给出了在FLAC3D中开发本构模型的基本步骤和编程要点，为其他用户进行本构模型的修改提供了借鉴和参考。由于FLAC3D开发环境的特点，用户编写的本构模型和软件自带的本构模型的执行效率处在同一水平。

Abstract

According to the further developing platform

the Duncan-Chang constitutive model is developed in FLAC3D with VC++ environment. A series of numerical simulations of triaxial tests are performed to verify the correctness of the compiled model. The provided basic procedures and programming essentials of the constitutive model redefining in FLAC3D offer a reference for other developers. Because of the characteristic of the development environment

a user-defined model has the same execution efficiency with the in-built model in FLAC3D.
