Abstract

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 proposed, 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 tunnel construction in districts where there is a strict surface subsidence demand, and as such, it is worth applying and popularizing.
