摘要
以大悟县环水河人行景观桥为例,总结了斜拉桥索力优化的目标,采用最小弯曲能量法对实例斜拉桥的索力进行了计算和研究,以主梁弯矩和整体位移为控制目标,对索力进行了优化,得到了能够指导施工的有效的索力结论。
Taking Huanshui River pedestrian landscape bridge in Dawu County as the example,the paper adopts the least bending energy method to calculate and research the cable force of the cable-stayed bridge,optimizes the cable force by taking the upper beam bending moment and overall displacement as the control target,and achieves the effective cable force to direct the construction.
