利用FLAC3D程序提供的二次开发平台UDM在VC++编译环境下实现了一基于修正剑桥模型的简化边界面模型的开发。介绍了边界面模型的基本原理,并给出了开发关键技术和具体实施方法。通过三轴加卸载试验、不排水静三轴试验、不排水动三轴试验等几种数值试验与修正剑桥模型进行了对比研究。计算结果验证了所开发的边界面模型的正确性及相对修正剑桥模型的优越性。
Using the secondary development platform UDM provided by the FLAC3D program, a simplified boundary model based on the modified Cambridge model is developed under the VC ++ compilation environment. The basic principle of the boundary surface model is introduced, and the key technologies and specific implementation methods are given. Through three-axis loading and unloading test, undrained static triaxial test, undrained triaxial test and several other numerical tests and modified Cambridge model were compared. The calculated results verify the correctness of the developed boundary model and the superiority of the relative modified Cambridge model.
