摘　　要：为了防止强夯施工振动对邻近建构筑物造成损伤,在施工过程中需要对重复性的瞬时振动进行实时安全监测,用以研究强夯振动对邻近建构筑物产生的影响。本文基于工程实例,介绍强夯振动安全监测原理、监测标准和监测方法,并对实测波形进行时程曲线分析、峰值振动速度及夯点与监测点的距离分析,确定观测期间强夯振动对周边的建构筑物影响程度,以期可为类似安全监测项目提供参考。In order to prevent the damage caused by dynamic compaction vibration to the adjacent structures,it is necessary to carry out real-time safety monitoring on the repetitive instantaneous vibration during the construction process to study the influence of dynamic compaction vibration to the adjacent structures.Based on an engineering example,the principle,monitoring standards and monitoring methods of dynamic compaction vibration and safety monitoring are introduced,and the time history curve analysis,the analysis of peak vibration velocity,the distance between tamping points and monitoring points of the measured waveform are carried out,the influence extent of dynamic compaction vibration to the adjacent structures are determined in order to provide references for similar monitoring project.
