Investigation of the Effects of Twin Tunneling on Ground Surface Settlement and Internal Forces of a Single Pile in 3D Analysis
In this paper, using the finite element analysis and 3D modeling in Abaqus, the effect of different patterns of twin tunneling by the New Austrian tunneling method (NATM) on the ground surface settlement internal forces of a single pile is investigated. For this purpose, three commonly used tunneling patterns in NATM, including top heading (TH), central diaphragm wall (CDW), and sidewall drift (SD), are taken into account. The effect of tunneling patterns on a single pile was also studied. Comparison of the results shows that the TH pattern has the highest and the CDW has the lowest surface settlements. It was observed that in the twin tunneling, the increase and decrease of the magnitude of bending moment applied to the pile depended strongly on the tunneling patterns. In addition, in all tunneling patterns, the effective zone of maximum axial force distributed on the pile is within ± 2D (D is the diameter of the tunnel).
