Cable Girder Anchorage Experiment and Stress Analysis of Extra-Dosed Cable-Stayed Bridge

This paper firstly introduces the PC beam's construction characteristics of Chongqing Jiayue Bridge and the simulated analytical result of the internal stress of the girder.The 1∶3 scale-down model test of the PC beam is established to verify the above calculation result.Finally,the applicability of cable-girder anchorage structure in the extra-dosed cable-stayed bridge of the PC beam is discussed,as well as the safety of the cable-girder anchorage structure under the kilo-ton cable force.Some useful conclusions and suggestions are presented concerning Jiayue Bridge's design and construction.
