摘要
当前强夯法施工在地基处理和加固中得到了广泛应用,强夯法施工振动引起的环境公害问题也日益得到工程界和有关部门的关注和重视。对广州花都空港变电站强夯场地开展了强夯振动对周边环境影响的监测试验,在监测试验中考虑了施工工况、锤型、锤重、落距、夯击次数对强夯振动传播的影响,并对隔振沟的隔振效果进行了测试分析,最后通过实测数据界定了安全距离。
Dynamic compaction method is widely used nowadays in foundation treatment and subsequently, the environment hazards caused by dynamic compaction are receiving more and more attentions from engineering applications and the relevant departments. The monitoring experiments are conducted for studying the effect of the dynamic compaction on the environment in transformer substation of Guangzhou Huadu airport. It is considered of the effect of the construction conditions, the type of the hammer, and the weight of the hammer, the height of the tamping and the frequency of the tamping on the propagation of vibration. In addition, the effects of the vibration isolation trench are analyzed, and a safety distance is determined from the experiment.
