偏压地层连拱隧道二衬开裂成因研究

Study on the Cracking Cause of Secondary Lining of Multi-Arch Tunnel in the Stratum with Partial Pressure

隧道的建设为公路线型设计、行驶时间减少、控制工程造价提供了更多的选择。但不可避免地出现了许多问题,例如,偏压地层对隧道施工和运营的影响等。针对偏压隧道施工中的二衬开裂问题,论文以二衬开裂的成因为研究方向,为隧道建设提供一些参考经验与技术。

Tunnel construction provides more choices for highway line design, driving time reduction and engineering cost control. But there are many unavoidable problems, for example, the influence of strata with partial pressure on tunnel construction and operation. Aiming at the cracking problem of the secondary lining in the construction of the partial pressure tunnel, this article chooses the cracking causes of secondary lining as the research direction, hoping to provide some reference experience and technology for tunnel construction.
