Preface

In the process of urban development, the subway construction is developing rapidly and the subway transportation network is increasingly improved, which brings great convenience for unban commuting. In oder to solve the traffic problems comprehensively and ensure people to travel conveniently, the subway construction has become people’s first choice. The subway construction project is very dangerous, during the process, any detail will cause safety liability accidents, especially in the process of subway tunnel construction, a slight mistake will cause safety accidents.
        The traffic engineering is a key content in our country’s modernization construction, it makes people’s daily travel more convenient and it can improve people’s quality of life. Under the trend of growing urban population, the subway tunnel can ease the traffic pressure, and it is also an important symbol of a modern city. In the process of construction, the control of construction technology should be strengthened to ensure the quality of subway tunnel project, thus to improve the safety of traveling. The construction technology should be based on the requirements of the projects and the characteristics of
construction area.
        Subway has become the main public transportation system in major cities, which has many advantages, such as comfort, throughput and safety. But due to the underground environment, it needs tunnel construction, thus it has a greater construction difficulty. Especially because most subway projects located in the city center, if the construction technology is not properly selected or the operation management is not in place, it may have an impact on the ground buildings.Therefore, it is necessary to conduct a in -depth research of subway tunnel construction technology and strictly control it.

前 言

在城市发展过程中，地铁工程建设如火如荼，地铁交通网络也日趋完善，为城市通勤带来极大的便利。为了全面解决交通问题，保证人们便利出行，地铁建设成为首选。地铁项目建设危险性大，进行施工过程中，任何一个细节都会造成安全责任事故，特别是地铁隧道施工更有难点，稍有不慎就容易出现安全事故。
        交通工程是我国现代化建设中的重点内容，为人们的日常出行营造了便捷的环境，是改善人们生活质量的关键。在城市人口数量不断增加的趋势下，地铁隧道建设能够缓解交通压力，同时也是一个现代化城市的重要标志。在实际施工当中，应该加强施工技术的控制，确保地铁隧道工程的质量，提升人们出行的安全性。施工技术的选择，应该以工程项目要求和施工区域特点为依据。
        地铁现在已经成为各大城市主要公共交通体系，具有舒适性强、运载量大以及安全性高等特点。但是对其施工特点进行分析，因为多处于地下环境，需要采用隧道形式施工，具有较大的施工难度，尤其是地铁工程多处于市中心位置，如果施工技术选择不当以及操作管理不到位等，均有可能会对地面建筑产生影响，必须要对地铁隧道施工技术进行深入研究和严格及控制。
