| Abstract: | 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. |
