采用节线法对悬索桥进行初始平衡状态分析，编制 MATLAB 计算程序，计算了实例的缆索线形及其无应力长度等主要参数；同时利用 MIDAS 对程序的计算结果进行了分析对比。最后以 MATLAB 计算结果为边界条件建立 ANSYS 有限元模型，进行结果分析，验证了节线法在进行悬索桥初始平衡状态分析时不很精确的结论。

In this paper,the initial equilibrium state of suspension bridge was analyzed by nodal line method.First,primary parameters such as form of cable line,length of unstressed section,etc.was calculated by using theMATLABprogram,and the results were compared to those byMATLABprogram.Finally,the results ofMATLABas the boundary condition,the finite element model was built by usingANSYS software.The results show that nodal line method is not precise enough in analyzing the initial equilibrium state of suspension bridge.
