[0002] The shield tunneling method is a fully mechanized construction method in the cut-and-cover method of tunnel construction. It is a construction technology commonly used in tunnel engineering today. The shield tunneling method involves advancing the shield machine in the ground, using the shield shell and segments to support the surrounding rock to prevent collapse into the tunnel. At the same time, cutting devices are used to excavate the soil in front of the excavation face, and the soil is transported out of the tunnel by the excavation machinery. The tunnel is then pushed forward by jacks at the rear, and precast concrete segments are assembled.
