摘要
强夯法在地基处理中被广泛应用,但施工振动经常对周边建筑物造成损害。为准确界定强夯施工振动对周边建筑物影响安全距离,基于强夯振动衰减规律和量纲分析方法推导建立了计算模型,并利用试验监测数据对模型参数进行了统计分析,经过实例验证分析,计算结果安全可靠,可为今后的强夯施工提供参考。
Dynamic comp action method is widely used in foundation treatment, but the construction vibration often causes damage to the surrounding buildings. In order to accurately define the influence of dynamic compaction construction vibration on the surrounding buildings, the calculation model of the construction safety distance is established based on the dynamic compaction vibration attenuation law and the dimensional analysis method, and the parameters of the model are analyzed by using the test data. The calculation result is safe and reliable supported by an example. It can provide reference for the construction of dynamic compaction in the future.
