随着国内城市轨道交通系统的发展,选择合理的施工技术成为一个重要的问题。盾构法施工技术为城市轨道交通系统的建设的重要技术之一。虽然其造价高,安装操作难度大,但它具有对地面结构影响较小、对环境无不良影响、地下水位可保持、对工作人员较安全、劳动强度低、进度快、机械化程度高、隧洞形状准确、质量高、衬砌经济等优点。盾构施工技术在城市轨道交通系统建设中的应用,要研究生产国内盾构机、盾构机的反复使用和长距离施工等问题。
With the development of the domestic urban rail transit system, the selection of reasonable construction technology has become an important issue. Shield construction method for the construction of urban rail transit system is one of the important technologies. Although its cost is high, it is very difficult to install and operate, but it has less influence on the ground structure and has no adverse effect on the environment. The groundwater level can be maintained. It is safer for the staff, has lower labor intensity, faster progress, higher mechanization, and tunnel shape Accurate, high quality, lining economy and so on. Shield construction technology in the construction of urban rail transit system to study the production of domestic shield machine, shield machine and the long-distance construction of the repeated use of such issues.
