摘　　要：从振动速度入手研究了强夯对沉箱的影响,通过选取一个有代表性的区域进行了试夯,确定了夯击能大小和夯击距离对沉箱振动的影响规律,进而合理选择夯击能及夯点安全距离,以保证施工的有效性和沉箱的正常使用寿命,对类似工程有很好的指导意义。Starting from the vibration speed,this article studies the impact of vibration on the caisson,selects a representative region for testing dynamic compaction,and determines influential law of dynamic compaction energy and dynamic compaction distance on the caisson vibration.Furthermore,it chooses rational dynamic compaction energy and safe dynamic compaction distance,so as to ensure the effectiveness of the construction and normal utilization life expectancy of the caisson,which has good guiding meaning for similar engineering.

关 键 词：强夯 沉箱 振动 安全距离
