| 摘 要： | 斜拉桥是一种高次超静定结构,索力的大小对结构的受力影响非常大,确定斜拉桥合理成桥状态的关键问题是如何控制斜拉索在成桥时的索力。该文以厦门某座斜塔斜拉桥为例,运用几种调索理论进行调索,进行比选后确定了适合本桥的成桥索力。

| Abstract: | The cable-stayed bridge is a highly redundant structure.The cable force greatly influences the bearing of the structure.The key issue to determine the rational completion status of cable-stayed bridge is how to control the cable force of the stayed cable when the completion. Taking an inclined-pylon cable-stayed bridge in Xiamen as an example,the article applies several cable adjusting theories to adjust the cable,and determines the completion cable force suitable for this bridge after the comparison. |
