| 摘 要： | 以卡罗波夫折减法为基础,提出了一种改进的计算斜拉桥桥塔稳定系数的方法——修正的弹性支承法.以目前世界上跨度最大的斜拉桥-苏通大桥为例进行计算,并将计算结果与有限元分析结果进行了对比.结果表明,在一定的施工状态、荷栽工况及参数条件下,该计算方法得到的桥塔稳定系数与有限元分析结果非常接近.修正的弹性支承法由于考虑了斜拉索的... |

| Abstract: | Based on the Carol Bove reduction method,an improved method,i.e.,modified elastic support method,was put forward to calculate the pylon's stability coefficient of cable-stayed bridge.The calculation based on Sutong Bridge,the longest span cable-stayed bridge in the world,was performed.The values obtained by the presented method were compared with the values gained by finite element method.The results show that(1) the stability coefficients calculated by the presented method and finite element method are clo... |
