【摘要】 本文针对折线形独塔斜拉桥这一新兴桥型,由于塔柱呈倾斜的折线造型,造成结构体系受力复杂,从而导致合理确定成桥索力困难的问题,以某折线形独塔斜拉桥为例,建立恒载索力优化模型,综合比较多种常用调索方法来优化成桥索力分布,确定同时满足折线形桥塔、不等跨主梁受力需求的合理成桥索力,为今后同类桥梁的设计提供参考。更多还原

【Abstract】 Kinked single pylon cable stayed bridge is a kind of new type of cable stayed bridges.Because of having a inclined and kinked pylon line to cause a more complicated mechanical system,there are many problems when the reasonable completed state is designed.Taking Tai Ping Zhuang-Bridge as an example,a new method of cable force adjustment to form reasonable completed state was presented in this paper by building a practical optimization model on cable force with dead load and comprising many general method of cable force adjustment.The results of the calculation prove that the method presented herewith is pretty effective and reliable,and also can bring valuable references for design and construction of similar bridges.更多还原
