| 摘 要： | 本文通过对倾斜地表重力作用下岩石的应力分析，把相对隧道截面埋置较深的圆形隧道问题看作弹性力学中无限板圆孔来处理，在计算方面采用分解叠加的等效原则把工程中遇到的复杂应力转化为简单应力，求解出一般条件下平面应变解析表达式。避免了繁杂运算，并且详细地讨论了影响隧道围岩应力分布的各项因素。

| Abstract: | Based on stress analysis of the rock under the action of gravity of declinedground,the deep tunnel with circular cross section is treated as a circular hole in infiniteplate from the viewpoint of elastic mechanics.For the calculation,an equivalent principle of decomposition and addition was applied which transform the complex stress into a simpleone to obtain an analytical equation of planar strain under general conditions thus avoidingtedious calculation.The factors influencing the stress distribution of surrounding rock in tunnel were discussed in detail . |
