摘要:
为研究服役期内产生材料性能劣化的连续刚构桥地震响应,以某在役高墩三跨连续刚构桥为对象,考虑氯离子侵蚀作用下材料性能劣化,基于相似原理构建实体模型进行振动台试验,得出模型桥梁在三向地震激励作用下结构的地震响应规律.三向地震波激励下跨中挠度受地震波影响程度较大,随着地震强度的增加,桥墩在横桥向更易受损.在实际工程中,应着重考虑对桥墩处进行加固处理.
Abstract:
To study the seismic response of a continuous rigid frame bridge that produces material degradation during service,Taking a high-rise three-span continuous rigid frame bridge in service, considering the deterioration of material properties under the action of chloride ion erosion, a solid model is built based on the similar principle for the shaking table test. The seismic response law of the model bridge under the excitation of three-way earthquake is obtained.The mid-span deflection under the excitation of the three-way seismic wave is greatly affected by the seismic wave. As the seismic intensity increases, the pier is more vulnerable to damage in the transverse bridge.In actual engineering, the reinforcement of the pier should be considered.
