| 摘 要： | 由于岩土材料的复杂性，FLAC3D软件自带的本构模型不能满足实际数值分析的全部要求。利用FLAC3D预留的UMD接口，在C++的编译环境下实现了一种基于临界状态模型CASM边界面模型的开发。介绍了边界面模型的基本组成，给出了开发的关键步骤。并基于三轴试验结果，利用该模型对饱和尾粉砂静/动力学特性进行了分析，论证了该模型对饱和尾粉砂的适用性。

| Abstract: | Due to the complexity of geotechnical materials, the constitutive model of FLAC3D software can not meet all the requirements of practical numerical analysis.Using UMD interface reserved by FLAC3D, a boundary surface model based on critical state model CASM is developed in C++ compilation environment. The basic composition of the boundary surface model is introduced, and the key development steps are given. Based on the triaxial test results, the static/dynamic characteristics of saturated tailings silt were analyzed by using the model, and the applicability of the model to the saturated tailings silt was demonstrated. |
