摘要
为探求列车运行所引起的桥下地面振动衰减规律,通过一系列现场测试,测得多组在不同车速下的地面加速度记录,对所得加速度记录进行计算处理,得到了各测点的最大加速度值.然后针对各测点的加速度比,运用复合回归方法。
In order to study the attenuation behavior of ground vibration under bridge caused by moving trains, a lot of ground acceleration data on the various train velocity are collected from series of in situ tests. The maximum acceleration values are obtained from the test data. Then compound regression method is carried out to study the attenuation empirical formula for ground acceleration under bridge induced by moving trains.
