Abstract

Abstract

The full-scale segmental model test and corresponding analysis were conducted on the assembly monolithic concrete utility tunnel with double compartments to obtain its mechanical performances. The results showed that:1) the failure mode for the larger compartment roof was shear failure after yield of longitudinal rebars, while the shear failure was observed in the smaller compartment roof before the ultimate flexural capacity. The shear bearing capacity of the roof with larger thickness for the tunnel was likely to be the control factor in design; 2) the working performance of the bonding interface could be guaranteed if the anchorage of the web rebars of trusses across the bonding interface was reliable; 3) the overlapping structure between U-shaped rebars reserved in the precast parts of walls and the rebars extending into the cast-in-place layer of the roof could meet load-bearing requirement of connections; 4) the structural design of the existing utility tunnel had sufficient safety reserve and good normal service performances.
