我国属于典型的人口与大国,人口基数庞大,近年来随着城市化建设的发展,交通环境问题变得更为突出。为了有效的缓解交通环境方面的压力,我国要求各级政府均能够有效领导并且致力于地铁的建造,以此保证城市交通运输环境的宽松和顺畅。在地铁施工当中主要能够涉及到的施工技术包括明挖法、暗挖法、降水法、冷冻法、盾构法、高压旋喷法等多种方法。本文主要针对地铁施工当中的暗挖法作出相应的分析。首先,本文对暗挖法施工的技术特点进行了阐述,其次明确了地铁施工当中可能存在的技术挑战。在此基础上,本文重点从某地铁项目车站施工以及地铁隧道施工当中对暗挖法的具体应用进行了研究。
As a typical population and great power, our country has a huge population. In recent years, with the development of urbanization, our transportation environment has become more prominent. In order to effectively alleviate the pressure on the traffic environment, China requires all levels of government to be able to effectively lead and commit themselves to the construction of the MTR to ensure a relaxed and smooth urban traffic environment. The main construction technologies that can be involved in the construction of the subway include various methods such as digging method, undercutting method, precipitation method, freezing method, shield method and high pressure rotary jet method. This paper mainly analyzes the undercutting method in subway construction. First of all, this paper elaborates the technical characteristics of undercut construction, and secondly, it identifies the possible technical challenges in subway construction. On this basis, this paper focuses on the specific application of undercutting method from the construction of a metro project station and subway tunnel construction.
