| 摘 要： | 以某自锚式斜吊杆悬索桥工程为背景，对该桥钢管桁架斜塔的力学性能进行分析。通过运用有限元软件对该桥主塔分别进行静力分析、特征值屈曲分析、几何非线性和材料非线性稳定性计算，得出在不同荷载工况下该桥的受力状态和稳定系数，并对计算结果进行分析。 |
| 关 键 词： | 钢管桁架斜塔 静力分析 特征值屈曲分析 稳定性 |

| Abstract: | Based on a self-anchored leaning derrick suspension bridge project,this paper analyzes the mechanical property of steel tube truss leaning tower of the bridge.After analyzing static force,and proper value buckle,calculating geometrical and material nonlinear stability of the king tower of the bridge respectively by means of finite element software,the strained conditions and stabilizing factors of the bridge under various load cases are acquired,and the calculation results are analyzed. |
| Keywords: | steel tube truss leaning tower static force analysis proper value buckle analysis stability |
