| 摘 要： | 以圆形洞室四层层状岩石围岩为研究对象,建立了弹性分析模型,推导了围岩应力区内的位移解。根据弹性力学中的平面应变理论,不考虑围岩的塑性变形,利用已知的应力方程、物理方程、几何方程,通过逐步分层而得到位移解。

| Abstract: | An elastic model is introduced to analyze the displacement of the stress area in an underground roundness tunnel,based on the study of the surroundingl rock of four layers interstratified.According to plane strain theory,based on stress equation,physical equation,geometrical equation,the computation is started firstly on the hypothesis that the stress area is a whole part,then it's continued with considering the area to be divided into two parts and then into four.Elastic deformation of the surrounding rock is neglected in this paper. |
