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。
At present, the application of dynamic compaction method has been widely applied in foundation treatment and reinforcement. The problem of environmental pollution caused by vibration during construction of the dynamic compaction method has also drawn increasing attention and attention from engineering departments and relevant departments. The monitoring test on the influence of dynamic compaction vibration on the surrounding environment was carried out on the compacted ground of Guangzhou Huadu Airport Substation. During the monitoring test, the construction conditions, hammer type, hammer weight, falling distance, The vibration isolation effect of the vibration isolating ditch is tested and analyzed. Finally, the safety distance is defined by the measured data.
