摘要
岩石的非线性蠕变本构模型的二次开发是研究岩石非线性蠕变的重点.本文对前人建立的本构模型进行三维差分公式推导,将三维公式写入FLAC3D软件,进行本构模型的二次开发;对比分析数值模拟和试验数据的拟合程度,验证模型的正确性.
Abstract
The secondary development of the nonlinear creep constitutive model of rocks is the focus of the study of nonlinear creep of rocks.In this paper,the three-dimensional difference formula of the constitutive model established by the predecessors is derived,and the three-dimensional formula is written into the FLAC3D software for the secondary development of the constitutive model.The fitting degree of numerical simulation and experimental data was compared and analyzed to verify the correctness of the model.
