摘要
建立了岩体非线性蠕变损伤演化方程,通过自行编制ABAQUS蠕变子程序,对圆形隧洞的开挖和蠕变后的力学行为进行了数值分析,实现了非线性蠕变本构模型的二次程序开发。
A user subroutine was programmed to incorporate the nonlinear creep damage evolution equation of rock mass in the finite element analysis software ABAQUS. With this user subroutine, the excavation of a circular tunnel and its subsequent mechanical behavior due creep were properly modeled.
