摘要
本文针对高跨比较小的三车道公路隧道，结合某工程设计的支护结构体系进行了模型试验研究，并进行了必要的有限元计算分析。重点研究了施工过程的各个阶段和使用阶段围岩及结构的力学行为，提出了低高跨比的支护结构体系的稳定性判据，对设计的原结构进行了安全度评价，并提出相应的建议。
In this paper,by the model test,authors study some design of support structure system with three-lane road tunnel of small-scale and high-span. At the same time,finite element method is applied to analyses this support structure system. Authors put emphasis upon studing the different stage of construction process and its mechanic behaviour of tunnel support and surrounding rock. Stability criterion of support structure system of small-scale and high-span is proposed,safety of original design of support structure system is determined, and some suggestions are put forward.
