In recent years, with the improvement of urban density, the limited available ground space has gradually become an important reason restricting the development of urban construction. The infrastructure and underground pipelines in urban areas put forward higher requirements for creating underground space. In tunnel construction, the traditional open cut method because of its long time covering construction, cut off traffic, electric power, water and gas supply pipeline defects, no longer apply to the city within the tunnel construction, and has little impact on the environment, the construction of high efficiency, green environmental protection shield method gradually get the wide attention from various asp. The term “shield” in the shield tunneling method has two meanings: shield refers to the cutter head and pressure chamber that can maintain the stability of the excavation surface of the stratum, and the steel shell that supports the soil around the tunnel; the structure refers to the lining structure of the tunnel segments and the grouting body behind the segments. Shield tunneling is a set of tunnel construction methods with shield tunneling as the core.
