摘　　要：对某隧道建立有限元结构分析模型,研究隧道初衬结构安全性及衬砌内力。结果表明,隧道衬砌结构在长期峰值水压力作用下安全度满足规范要求,结构安全稳定。计算隧道二衬结构内力值,并将数值模拟结果与实测数据对比分析,得出应力分布规律,两者一致,边墙和仰拱处为受力最不利位置。In this paper,a finite element structural analysis model is established for a tunnel to study the safety and lining internal force of lining structure.The safety of tunnel lining structure under long-term peak water pressure satisfies the requirements of the specification and the structure is safe and stable.The internal force of the tunnel lining is calculated,and the numerical simulation results are compared with the measured data to get the stress distribution law.Both of them show that the inverted arch and the side wall are the most unfavorable position.
