结合某高速公路互通匝道桥抗倾覆验算的工程背景,运用空间有限元方法进行分析,在考虑不同荷载工况组合的情况下,对主梁的抗倾覆稳定性进行分析,结果表明:选择针对性的车辆荷载进行抗倾覆验算,才能保障桥梁的运营安全。
Combining with the engineering background of anti-rollover checking of an express highway interchange ramp, the finite element method is used to analyze the stability of the anti-rollover of the main girder under the combination of different load conditions. The results show that: Of the vehicle load anti-overturning checking in order to protect the safety of the bridge.
