Abstract: Taking（120+120） m single-tower cable-stayed T structure composite bridge as the background, the stress distribution of concrete and cable saddle in the anchorage zone of filament pipe and cable tower was studied. The local finite element model of the cable pylon segment was established by ABAQUS software. By simulating the contact relationship between the cable and the cable saddle, the spatial stress distribution state of the concrete and the cable saddle in the anchor zone of the cable pylon was studied and compared with the equivalent surface load analysis method. The results showed that the contact analysis was closer to the actual force situation than the surface load analysis, and can accurately simulate the transverse deformation of the cable and the influence of unbalanced cable forces on both sides of the cable pylon.
