通过现场测试结合有限元模拟计算结果,分析了某连续箱梁桥运营过程中振动过大的原因,并给出了相应的处治方法。实践证明:该方法具有较好的可实施性,能有效减小独柱墩桥梁在车辆作用下的振动,可为同类桥梁的振动病害处治提供借鉴和参考。 Through the field test combined with the finite element simulation results, the reason of excessive vibration during the operation of a continuous box girder bridge was analyzed and the corresponding treatment methods were given. Practice has proved that this method has good implementability and can effectively reduce the vibration of single-pillared bridge under the action of vehicle, which can provide references for the treatment of vibration diseases of similar bridges.
