振动在桥梁工程中的应用

在桥梁工程中,为了延长桥梁的使用寿命,当车辆通过桥梁时,必须对车辆的行驶速度加以限制,以免使桥由于共振而遭到破坏,致使交通不便及不应有的经济损失。本文仅对稳定载荷和非稳定载荷通过桥梁时所引起的共振分别进行了论述。

The Vibrance was Used in the Bridge Engineering

In the bridge engineering ,when vehicals cross the bridge, their acceleration must be restricted in order to ensure the bridges long life,in case that the bridge was damaged causing traffic crowd and economic loss owing to co-vibration, This article states the co-vibration caused by the steady load and unsteady load when vihicals cross the bridge.
