| 摘 要： | 采用平面及三维有限元数据计算方法，对复杂地质条件下小间距双线城市交通隧道的围岩稳定特征进行了分析，并对现有小线间距条件下厦门莲黄隧道围岩及结构的稳定性进行了评估，同时，模拟计算还可为围岩的预加固提供科学的依据，研究成果不仅可以评 莲黄隧道的安全施工问题，还可对我国小净距公路并行隧道施工技术的发展产生积极的推动作用。

| Abstract: | The stability of wall rocks on double small-interval urban tunnels has been analyzed under complex geological condition by applying 2D and 3D FEM numerical simulation.The stability of wall rocks and structure of Lianhuang Tunnel in Xiamen are analyzed in the case of small interval.In addition simulation calculation presents scientific grounds for pre-reinforcement of wall rocks. It is not only appled in evaluation of the safety of construction of Lianhuang Tunnel,but also taken as a reference for development of construction technology of parallel tunnel on small-interval highway tunnel in China. |
