摘　　要：强夯法可有效加固电力设施地基基础,但由于大能量夯击能的扩散,会对周边建筑物与居民产生一定的负面影响。结合强夯施工现场条件,对周边建筑物进行振动监测,测出不同距离下的振动速度,拟合出振动速度-夯检距关系曲线,并计算出建筑物安全距离。采用1/3倍频程分析法,计算建筑物内人体舒适度的容许振动加速度级,进而推算出人体舒适度符合规范容许值的距离节点。结合工程实践,计算得到强夯施工对周边建筑物的安全距离约为35m,建筑物内符合规范的人体舒适度距离约为90m。The dynamic compaction method can effectively strengthen the foundation of power facilities,but due to the diffusion of large-energy ramming energy,it has a certain negative impact on surrounding buildings and residents.Combined with the construction site conditions of dynamic compaction,the vibration of surrounding buildings is monitored,and the vibration speeds at different distances are measured.The relationship curve between vibration speed and compaction distance is fitted,and the safety distance of the building is calculated.The 1/3 octave analysis method is used to calculate the allowable vibration acceleration level of human comfort in the building,and then calculate the distance node where the human comfort meets the allowable value of the specification.Combined with engineering practice,it is calculated that the safe distance of dynamic compaction construction to surrounding buildings is about 35 m,and the human comfort distance within the building that meets the specifications is about 90 m.
