| 摘 要： | 斜拉桥的索塔锚固区受力情况较为复杂,在对该区域进行设计计算时,常采用实体建模计算结构各点的应力来评价结构的安全性,这种方法不仅繁琐,而且力学概念不清,往往不能得到最优结果。针对斜拉桥索塔锚固的塔壁锚固形式进行简化分析,研究了索塔锚固区环向预应力简化设计理论及其计算方法,该方法能够适应目前大多数斜拉桥的设计计算,具有较高的工程实用价值。

| Abstract: | The force is very complex in the anchorage zone of cable and tower.The stress result of structure solid model is often used to evaluate the structure security,this method is not only cumbersome but also unclear of the mechanical concepts,so often cannot get the actual results.The tower-wall anchor form of cable-stayed bridge is simplified to analysis force and stress.This paper achieved the simplify design theory and its calculation method,which can adapt to most current cable-stayed bridge design calculations,with more high practical value. |
