摘　　要：通过某铝厂强夯地基处理的工程实践,对回填碎块石土进行强夯振动时所产生的地面振动进行了现场监测,分析强夯振动的特征及振动速度衰减规律,评价隔震沟的减震作用及效果,根据设计的强夯参数进行强夯施工,使强夯振动对周围建构筑物造成的危害大为降低.Based on engineering practice for dynamic compaction groundsill processing of an aluminum plant,on-site monitoring on backfill compaction gravelly soil of ground vibration generated by dynamic compaction vibration was carried out.Through analysis on characteristics of dynamic compaction vibration and its velocity attenuation law,the damping effect of isolation trench was evaluated.The damages caused by dynamic compaction vibration on surrounding buildings and structures have been greatly reduced due to the dynamic compaction construction which was conducted according to designed dynamic parameters.

关 键 词：强夯振动 振动速度 隔振沟 建构筑物
