摘要
为探究某连续梁-拱组合桥挂篮反向预压牛腿支架的力学性能,首先明确了挂篮牛腿托架的设计参数和材料设计强度;其次给出了挂篮在使用过程中可能存在的荷载类型及荷载组合方式;最后结合有限元模型,对挂篮的反向预压施工进行了结构计算,并对其结构力学性能进行了分析。计算结果表明:该连续梁-拱组合桥挂篮反向预压牛腿支架力学性能满足施工过程中各种荷载及最不利要求。
In order to research the dynamic performance of some reverse prestressed bracket for suspended baskets on continuous beam-arch combination bridges,the paper identifies the design parameter and material design strength of the suspended basket’s bracket,provides the possible loading types and the loading composite means in the process of using the suspended basket,undertakes the structural calculation of its reverse prestressed construction by combining with the finite element model,analyzes its structural dynamic performance,and proves by the results that dynamic performance of the reverse prestressed bracket for suspended baskets on continuous beam-arch composite bridges meets the demands of all kinds of loads and unfavorable requirements in the construction.
