摘　　要：在强夯施工过程中 ,地面振动对周围环境的影响已是一个不容忽视的问题。借用弹性半空间理论中刚性基础瞬态振动的位移解 ,提出了估算强夯地面振动竖向速度峰值的半经验公式。工程实例的实测数据验证了半经验公式的可靠性 ,可为强夯振动环境效应评价提供有益的参考。Vibration generated by dynamic compaction is often detrimental to the surrounding neighbourhood.Based on elastic half space theory for a rigid dynamic machine foundation, a method for the maximum peak of vertical velocity of ground vibration caused by dynamic compaction is presented. Agreement is found with the result obtained in field tests. The method can be a useful reference for environmental impact evaluation.
