摘要
通过对斜拉桥索塔稳定性计算进行分析 ,提出了一种适合于索塔稳定安全系数计算的能量法 ,利用该方法对洞庭湖三塔斜拉桥中塔稳定性计算分析表明 :采用此方法计算斜拉桥索塔稳定安全系数可大大节约机时 ,并且结果具有很好的精度 .
In the paper, based on the analysis of the calculation of the stability of towers of cable stayed bridges, an energy method which is suitable for calculating the stability safety coefficient of towers of cable stayed bridges is presented. The stability of towers of Dongtinghu three towers cable stayed bridge is calculated. The results show that much time of computer calculating is saved and the accuracy of calculation is achieved.
