Experimental research on full-scale model for anchorage zone of pylon of cable-stayed bridge with illegal-shaped section

In this paper,the construction technology for prestressed tendons of main tower is researched through test of full-scale model of anchorage zone of pylon of Songhuajiang River Bridge of freeway surrounding Harbin;stress distribution and deformation condition of model under ring prestressed tendons and cable force are analyzed;safety factor for cracking resistance of tower is obtained by full-scale model test for anchorage zone of this bridge tower.Numerical simulation on this model is carried out,and some important conclusions are drawn by compared to FEM results and the test results.Parts of the achievements of study have been applied to real bridge work,and give some advices to the optimum design of the bridge tower.
