基于综合方法的斜拉桥合理成桥索力确定

Determining Rational Completion Cable Forces of Cable-stayed Bridges Based on Comprehensive Method

确定斜拉桥合理成桥状态的关键问题主要在于如何控制斜拉索在成桥时的索力。基于大量的中外文献,通过对当前相关研究成果的优缺点进行评述和比较,可提出综合采用刚性索法与自动调索法确定合理成桥索力的原理及步骤。通过算例证明,该方法概念明确,计算方便,所得结果满足要求。

The key point of determining rational completion state of cable-stayed bridge lies in how to control the home and abroad, commented. Thus it cable forces when completing cable-stayed bridge. On advantages and disadvantages of related research is put forward to adopt synthetical rigidity cable method the basis of document at fruits are compared and and automatic adjustment method of cable forces to ascertain the principles instance indicates that the concepts are explicit and Furthermore the results meets the request and the calculations are convenient in e forces. One this method.
