桥梁施工临时支撑结构稳定性分析

Stability Analysis of Temporary Support Structure for Bridge Construction

压杆稳定理论在桥梁施工临时支架中应用最普遍。通过压杆稳定理论对临时支撑结构进行稳定分析,结合工程实例,运用Midas Civil软件对重庆红岩村立交A匝道桥梁AP3支撑架进行有限元分析,分析其低阶模态下的整体稳定性,从而得到约束是稳定性的关键影响因素的结论。

The theory of pressure rod stability is most commonly used in the temporary bracket of bridge construction,Stability analysis of temporary support structure by pressure rod stability theory,combined with the engineering example,the finite element analysis of the AP3 Tower of the intersection.A Ramp Bridge of Chongqing Hongyan Village is carried out by using Midas Civil software to analyze the overall stability.Thus getting the constraint is the conclusion of the key influencing factors of stability.
