| 摘 要： | 通过对某斜拉桥桥塔节段足尺寸模型进行荷载试验,对该桥桥塔的锚固区工作性能及安全性进行了评价,此次试验采用由工字钢及钢板制作的传力装置,将斜向加载转化为水平加载,其传力效果良好。在此基础之上建立有限元数值计算模型,对桥塔节段锚固区应力进行了分析,并提出构造及设计上的建议,为工程实际做出了良好的指导。

| Abstract: | By means of model experiment on a full size model of anchorage zone section which was based on some cable stayed bridge tower,the evaluation of the anchorage zone of bridge tower's operating capability and safety was brought forward,the force transporting device made by I iron was used in the experiment to convert inclined loads to horizontal loads and its effectivenss was good.According to the results,the FEM model was built to analyze the stress field in anchorage zone of bridge tower.Some suggestions about constitution and design were given to guide the construction. |
