摘要: 根据混凝土斜拉桥合理成桥状态的确定原则、影响因素与确定方法,先用最小弯曲能量法初定成桥状态,再用影响矩阵法进行索力调整,获得了合理的成桥状态。运用该方法对某桥进行了计算,算例表明该方法简单、有效。

关键词: 斜拉桥, 合理成桥状态, 索力优化

Abstract: In terms of the determining principles,influential factors and determining methods of the reasonable finished dead state of the concrete cable-stayed bridges,a comprehensive method is developed.The procedure of this method is: deciding the initial dead state by using the minimum bending energy method firstly;then optimizing the cable forces by using the influence matrix method.And finally the reasonable finished dead state is determined.This method is used to calculate an actual bridge,and the result of the example shows that it is easy to operate and effective.

Key words: cable-stayed bridge, reasonable finished dead state, optimization of cable force
