缆索吊塔架结构选型与受力性能的可行性论证

以怒江四线特大桥为背景,围绕大桥工程中的缆索吊装系统展开分析,重点讨论了独立式钢管塔架。基于midas Civil进行了建模分析,得知塔架各构件对应的内力等指标都达到行业标准,验证了施工方案的可行性。将理论应用于实际工程中,发现钢管塔架的结构受力状态良好;通过优化塔架的选型设计,可以在确保工程质量的同时缩短工期。总体来说,方案的可行性较佳,具有可供参考的价值。

Feasibility Demonstration of Structural Selection and Mechanical Properties of Cable Suspension Tower

With the background of the four-line railway bridge across Nujiang River,an analysis was carried out around the cable hoisting system in the bridge project,and the independent steel tube tower was mainly discussed.Based on midas Civil s modeling analysis,it was learned that the internal forces and other indicators corresponding to each member of the tower have reached the industry standard,and the feasibility of the construction plan was verified.Applying the theory to actual project,it is found that the structure of the steel tube tower is in good condition;by optimizing the design of the tower,the construction period can be shortened while the construction quality is ensured.The scheme is feasible and has value for reference.
