Ground Surface Deformation Analysis of Quasi Rectangular EPB Shield Tunneling

Conference paper


The first quasi rectangular shield tunnel in China was developed during the construction of Ningbo Metro Line 3. Based on the Mindlin solution, this paper presents the computerized outcome of the ground surface deformation caused by the following three factors: the horizontal excess pressure at the excavation face, the friction between the shield skin and soil, and the grouting force outside the tailskin. The result shows: (1) Superposition of these three factors causes large surface heave near the tunneling area, with a maximum of 15 mm; (2) Grouting force plays an absolutely dominant role in ground surface deformation, which can cause a maximum 19 mm ground heave; (3) However, the total ground surface deformation induced by these three factors remains controllable. This study can be used for disturbance-control of future quasi rectangular shield tunneling.
