摘　　要：隧道衬砌与围岩的应力分析是隧道设计中一个重要内容。本文基于厦门市东通道海底隧道对圆形隧道衬砌与围岩应力的封闭解析解法进行研究,首先利用MATLAB编制衬砌与围岩应力程序并选用一个已有精确解的实例进行校验,然后对圆形隧道四种工况进行计算并给出相关的衬砌和围岩的分布曲线,最后对计算结果进行了相关分析。The stress analysis for tunnel lining and surrounding rock of tunnels is an important task in tunnel design.In this paper,analytical solution to lining and surrounding rock stress of circular tunnel is studied based on submarine tunnel for Xiamen east corridor.Firstly the program is compiled by means of MATLAB software and has been valid through a project which has explicit solutions. Secondly tunnel lining and surrounding rock stresses of four cases are depicted.Finally,the obtained results are studied and the authors put forward a few suggestions.
