| 摘 要： | 对于斜拉桥索塔的拉索锚固区，一般的力学模型分析难以全面反映结构的实际工作状态和承载能力。杭州市文晕路立效桥主孔结构为（104 204 104）m的三跨双塔双索面斜拉桥，根据该桥索塔构造及预应力束布置特点，设计了索塔节段足尺模型试验方案，并进行了空间有限元分析，给出了空间分析的一些主要成果及与试验实测值的比较，得到了许多重要结论。其设计建议对指导该大桥的建设具有重要的指导作用。

| Abstract: | A gneral 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 theconstrucation of Wenhui Road bridge. |
