移动支护技术及其在城市地下工程中的应用前景

Mobile Support Technology and Its Application Prospects in Urban Underground Engineering

城市空间的集约化发展为地下工程发展提供了良好的发展机遇,同时也对地下工程建设技术提出了更高的要求。本文结合盾构法和浅埋暗挖法,提出了一种适用于软土隧道的移动支护技术,并研究了其对地层变形的控制作用,数值分析和现场试验研究表明该技术具有很好的控制地层变形的作用。该技术在城市近距离穿越工程和对地表沉降控制严格地区的隧道施工中具有显著的优势,值得应用和推广。

The intensive development of urban space provides a good opportunity for the development of underground engineering. At the same time, it also demands higher requirements in terms of underground construction technology. In this paper, combined with the advantages of the shield method and shallow tunneling method, a mobile support technology suitable for soft soil tunneling is pro- posed, and its control effect on ground deformation is also studied. Numerical analysis and field tests show that this technique has a strong ability to control ground deformation. This technique has remarkable advantages in urban short-distance crossing engineering and tunmnel construction in districts where there is a strict surface subsidence demand, and as such, it is worth applying and popularizrag.
