钢引桥压载试验与理论计算分析

Steel bridge ballast experiment and theoretical calculation analysis

分析了压载试验中钢引桥的应变和挠度等试验数据,对钢引桥按刚架计算模型、桁架计算模型和空间结构进行了有限元计算,并与试验数据进行比较分析,探讨了不同计算模型的准确性及桥面系对主桁架弦杆的影响。

It analyses the experimental data of strain and flexibility of steel bridge in ballast experiment, makes the finite dement calculation to the steel bridge rigid frame calculating model, truss calculating model and space structure, compares and analyses them with the experimental data, and discusses the affection of the accuracy of different calculating model to the chord of primary truss.
