摘要
在文[1]工作的基础上,本文进一步探讨了地下工程围岩应力分析中围岩泊松比μ对有限元计算精度的影响.在此基础上,笔者应用数理统计的理论提出了确定围岩泊松比的工程方法,供地下工程结构设计工作者参考.
In this paper based on the literature in , the author has studied fur-ther the effect of poisson's ratio of rook on the calculating accuracy of the FEM in the stress analysis of the surrounding rock of underground engineering. Based on this, the author has developed simple and convenient methods, according the theory of mathematical statistics, with which the value of poisson's ratio of rock is determined and the corresponding inaccuracy is estimated, thus providing reference to the designer of underground engineering.
