地铁隧道纵向变形影响因素的探讨

A Discussion of the Factors Effecting on Longitudinal Deformation of Subway Tunnel

地铁的建设促进了城市经济的发展和地下空间的利用 ,但沿线地区的城市建设引起了地铁隧道的纵向不均匀变形 ,给地铁的安全带来了威胁 ,本文结合上海地铁和城市建设的发展 ,简述了影响地铁隧道纵向变形的因素 ,以期为地铁隧道的设计者和相关管理人员参考。

The construction of subway promotes the economy of cities and utilization of underground space. However, the construction along subway induces the asymmetric deformation of the tunnel, those deformations threat the safety of the subway. Based on the construction of city and subwqy in Shanghai, this paper discusses the factors effecting on longitudinal deformation of subway tunnel and provides a reference for designers of subway and involved management members.
