为了研究高架路交通引起的环境振动实际情况及振动传播规律,通过对广州某高架桥环境振动进行现场实测,比较了各测点不同方向上振动情况,得出了预测高架路交通引起环境振动的振级统计回归公式,建立了桥墩-桩-土体ANSYS模型,模拟结果与实测结果符合较好。
In situ experiment has been done on the environment vibration of viaduct traffic, so does the numerical analysis on the law of vibra- tion attenuation. Compared with vibration situation on differentdirections of various measuring points, established the statistical regression formula about vibration level in order to forecast the attenuation law of vibration aroused by the viaduct traffic. Established the bridge pier-pile-soil mass model, the numerical analysis results agreed well with experimental results.
