并行隧道围岩应力的线弹性分析
摘要:间距较小的并行隧道,两洞室开挖的相互影响不能忽略。引入双圆洞室围岩应力函数的线弹性方程,并通过编程实现工程计算,探讨了间距较小的并行双圆隧道围岩的应力特点以及应力随净距改变的变化规律,为间距较小的并行隧道围岩状态的定性判断提供了依据。
Abstract:The stress analysis is very important in tunnel design. Many results are obtained for the case of single tunnel. Due to the influence of each other, the analysis for two circular tunnels is difficult by mathematic method. The linear elastic problem of surrounding rock of two circular tunnels are studied by means of complex variable method. Through engineering examples, the characteristics of stress of two circular tunnels are obtained, and the obtained results can be applied to the analysis of two circular tunnels.
