摘　　要：当前形势下,由于城市的快速发展,通过盾构机进行城市轨道的交通挖掘工艺已日趋成熟,出入段线隧道设计及老城区受到地面上的建(构)筑物等因素的影响,以至于经常有小半径曲线的隧道路线,因此国内更加注重城市关于建造大量轨道的交通工程的规划。城市轨道交通为居民带来了极大的便利,并且对交通压力进行了有效缓解。以武汉市地铁7号线香港路—三阳路右线区间小半径曲线隧道(R=340m)为例,对小半径曲线隧道施工质量的控制要点、轴线的控制措施和地面沉降的控制等一些列措施进行分析、探讨,旨在为同行业者提供借鉴和参考。Under the current situation, due to the rapid development of the city, the city rail traffic shield mining has become increasingly mature, access line tunnel design and the old city is on the ground of the building（structure） of buildings and so on, so that the tunnel route often have small radius curve, so the domestic pay more attention to traffic on the construction of a large number of engineering city track planning.Urban rail transit has brought great convenience to the people, and has eased the traffic pressure effectively.This paper takes the Wuhan City Metro Line seven Hongkong Road, Sanyang road section of small radius curve right line tunnel（R=340m） as an example, the construction quality control points, the small radius curve of tunnel axis and control measures of ground subsidence control and some measures are analyzed and discussed, and provide the reference for the same industry.
