隧道由于地质施工等因素经常存在空洞和裂隙,这样会影响到衬砌的稳定性和安全性。本文现以某隧道工程为依托,利用有限元软件进行数值模拟,对隧道拱顶处存在空洞或裂缝时二次衬砌结构的受力状态进行了模拟分析,为隧道衬砌加固改造提供了理论支撑。

Due to the factors such as geological construction, tunnel often exist holes and cracks, which wil affect the sta-bility and safety of the lining. This article basis on a certain tu-nnel engineering, and uses the finite element software to carry on the numerical simulation, simulates and analyzes the stress of the secondary lining structure when there is a hole or crack in tunnel vault, which provides theoretical support for tunnel lining reinforcement and reconstruction.
