摘要
对强夯施工引起的场地和建筑物的振动效应进行现场测试,测得了距离强夯振源不同距离处的质点振动速度和主振频率,采用回归统计的方法获取该场地强夯振动波的衰减规律。通过与现有标准给出的振动参量进行对比分析,探讨了强夯施工振动对相邻建筑影响的评价方法。
Due to dynamic compaction construction,site and buildings suffer vibration effects.On-site test was conducted to measure vibration velocity and main vibration frequency of the particles with various distances from vibration source.The method of regression statistics is adopted to obtain the attenuation characteristics of vibration waves.Compared with vibration parameters suggested by existing codes,evaluation method of vibration effects of the dynamic compaction on adjacent structures is discussed.
