| 摘 要： | 对应力空间下的屈服接近度概念进行了重新定义,使其能更广泛地适用于各种材料的强度准则.同时,指出了文献中基于Mohr-Coulomb强度准则屈服接近度函数推导过程中存在的问题,对屈服接近度函数进行了重新推导与修正.在此基础上,对适用于不同材料的多个强度准则,推导了相应的屈服接近度函数,并给出了统一的表达式,以便数值计算程序的编写.最后,结合青岛市地铁3号线工程,在有限元分析的后处理阶段嵌入屈服接近度函数计算自编程序,实现对隧道围岩的可视化安全性评价.

| Abstract: | Yielding approach index (YAI) in stress space was redefined for general application to various strength criteria in this paper. Some problems in YAI function derived on the basis of Mohr-Coulomb strength criterion were pointed out and the function was re-derived and revised. Furthermore, a series of YAI functions for different material strength criteria were derived and expressed uniformly for convenient numerical programming. Finally, the stability and safety of the surrounding rock for an engineering (Qingdao Metro Line No. 3) were visually analyzed by embedding a self-compiling YAI program in the post-processing stage of finite element analysis. |
