摘要：

地面出入式盾构法隧道新技术省略了用于盾构始发与接收的工作井，在地面与地下连接区域用盾构掘进替代大开挖施工，具有环境影响小和建设工期短的显著优势，在中国属首次研发应用。该技术存在结构变形、接缝渗漏和轴线偏离等工程难题，以南京机场线地面与地下过渡段示范工程为背景，通过理论计算、三维仿真和模型试验等方法，重点阐述隧道变形、防水和盾构姿态控制等关键技术，并将其成功应用于示范工程，验证了GPST新技术的可行性和有效性，为推广应用提供了理论和实践支持。

Abstract:

It is the first time that Ground Penetrating Shield Technology (GPST) has been developed and applied in China. For the sake of the GPST, the shield launching shaft and the shield arriving shaft needed by conventional shield tunneling technology can be cancelled, the connection section between the underground tunnel and the aboveground tunnel can be bored by shield, the influence of the tunnel construction on the environment can be minimized and the construction period can be shortened. Therefore, GPST has great advantages. However, GPST has disadvantages related to structural deformation, joint seepage and axis deviation. In the paper, the control of the deformation of the tunnel structure, the waterproofing of the tunnel and the control of the posture of the shield are studied by means of theoretical calculation, 3D simulation and model test, with the connection section between the underground tunnel and the aboveground tunnel of the airport line of Nanjing Metro as an example. The study results have been applied in the construction of the mentioned works, which proves that the GPST is feasible and effective. The paper can provide theoretical and practical support for the further application of GPST. 
