流冰对佳木斯松花江公路桥梁的动力反应

Dynamic reaction caused by drift ice to Jiamusi Songhuajiang River Highway Bridge

结合工程实例介绍了季冰性河流流冰对桥梁基础的动力作用。通过对桥墩在浮冰撞击下水平位移的观测,提出了计算撞击力的方法。

Combined with the practice the dynamic reaction to the bridge base caused by the river drift ice in seasonal region. Though the observations on the level displacement arising out of the drift ice bump against the piers a method is provided to calculate the force.
