摘要
为保证现役铁路旧桥梁的安全运行,需定期对其进行检测。通过对清绿支线黑河1#钢桁架桥在列车通行时仪器所测实际值和利用有限元分析软件MIDAS/CIVIL 2010对该桥进行模拟所得理论值的分析比较,判断该桥承载力是否满足规范要求,最终为桥梁的加固和维护提供重要依据。
In order to ensure the safe operation of the active and old railway bridge, it is necessary for the bridge to do a detection at regular time. The actual value can be tested by the instrument when the train passes 1 # steel truss bridge of the Qinglv branch in Heihe. The theoretical value is simulated by the finite element analysis software of MIDAS /CIVIL 2010. And then, to determine whether the bearing capacity of the bridge can meet the specification or not, it is requisite to compare and analysis both of them. Ulti- mately the conclusion can provide the important basis for the conservation and maintenance of the bridge.
