摘要
讨论城市轨道交通工程建设中出现的问题:虽然盾构法隧道施工技术得以普及运用,但由于小半径曲线隧道盾构施工技术的特殊性和复杂性,将直接影响工程项目的成本、安全、质量与进度。通过分析小半径曲线地铁隧道盾构法施工易出现的问题,结合某盾构区间的小半径曲线隧道工程实例,阐述曲线隧道盾构施工技术的运用,为今后类似工程的施工提供一定的参考与借鉴作用。
Along with the development of metro tunnels, shield tunneling is increasing. Shield tunneling on curves with small radius involves complexities and difficulties, which directly affects the safety, quality and the problems that usually occur progress. This article analyzes under such condition. Based on the shield tunneling in a running tunnel on a small - radius curve, it introduces the tunneling technologies, which can be served as guidance to similar projects.
