斜拉桥施工索力确定的简易调索法

Simplifiedmethod to determinate the construction cable force for the cable-stayed bridge

鉴于斜拉桥传统调索理论与过程过于复杂,提出了手动调索的简易方法:通过数据处理,估算、优化索力,利用有限元软件进行迭代校核。介绍了该方法的详细步骤,并结合工程实例验证其可行性。

Without the complexity of the traditional cable force determination theory and method,a simplified method is presented.Using excel for data processing,cable force estimation and optimization and using the finite element software for iteration and verification to realize it.Detailed steps are introduced with feasibility verified by an engineering example.
