The Full-scale Model Test and Spatial Analysis for the Segment of Cable Pylon of Cable-stayed Bridge

A general mechanical analysis is hard to reflect the actual working status and carrying capacity for the anchorage zone of cable stayed bridge. The main span structure of Wenhui Road elevated bridge is a three span (104+240+104) m cable stayed bridge with two pylons and two cable planes,based on the conformation and characteristic of strand layout in cable pylon of this bridge, the test project of the full scale model of segment of cable pylon is described, the spatial analysis of segment model is carried through, the values obtained by spatial analysis and test results are compared, some important conclusions are drawn, it is beneficial to the construction of Wenhui Road bridge.
