ABSTRACT:

The immersed tunnel with steel-concrete-steel composite structure, as a novel type of tube structure with high efficiency of headroom, has been applied as the main structure in Shenzhen-Zhongshan Link Project. In order to analysis the mechanic behavior of the immersed tunnel, a three-dimensional solid nonlinear finite element model was established based on standard loads and actual boundary conditions. The lateral force mechanism of the structure is revealed by showing the stress distribution of the steel structure, the concrete structure, and the force distribution of connectors. It could be concluded that the lateral bending resistance of the tunnel is mainly provided by the upper and lower steel plates and the core concrete. The shear resistance is mainly provided by the transverse stiffening steel plate and the concrete. Also, the distribution of shear force between steel and concrete transferred by connectors is presented. The combination of T-stiffener and studs can ensure the bonding of the two materials. The shear force in the shear region is larger, and the pull-out force in moment region is larger.
