| 摘 要： | 结合已有常规斜拉桥断索行为研究，运用MIDAS／CIVIL有限元分析软件对某双塔单索面矮塔斜拉桥进行计算，对不同断索情况下及未断索情况下该桥的拉索索力、主梁线形、索塔偏移量及自振频率进行对比分析，得到该桥力学特性随断索位置及断索长度的变化规律。

| Abstract: | In combination with research on behavior of broken off cables of existing conventional cable- stayed bridges, this paper calculates some low double-tower and single cable plane cable-stayed bridge by means of MIDAS/CIVIL finite element analysis software, and performs comparative analysis for force of inhaul cables, girder alignment, offset of cable tower and natural frequency of vibration of the bridge in the cases that cable are broken off and not broken off to obtain the change laws of mechanical properties of the bridge with position and length of broken off cables. |
