| 摘 要： | 本文通过对三种典型洞型的三维有限元分析研究,给出了与以往认识不同的几个概念,并为在巷道围岩稳定性分析时,适当地作二维简化给出了一个较合理的范围。另一方面,为在平面有限元分析和反分析中考虑空间效应、确定释放荷载系数提供了重要的参考依据。

| Abstract: | By studying three dimentional FEM analysis of three typical caverns, the paper gives some concepts different from those in the past, and describes a reasonable region for simplifying spatial problem into plane one. An important reference basis is provided for considering spatial effect and determining release load coefficients in plane FEM analysis and back one. |
