摘　　要：由于爆破施工振动对周边建筑物影响引发不少民事纠纷,已成为社会关注焦点,以中山市某工业厂房附近山坡爆破试验场地为例,论述了基于有限差分软件FLAC 3D的爆破振动对周边建筑物影响的数值分析方法,模拟结果表明爆破振动三向速度峰值大小为Z向>X向>Y向,模拟计算结果与监测数据总体一致,采用数值分析方法与采用现场监测方法进行爆破周边建筑物安全界定评判结果一致,研究成果可为今后爆破施工周边建筑物的安全评估提供参考和借鉴。As the impact of blasting vibration on surrounding buildings has caused many civil disputes,it has become the focus of public concern.Taking the hillside blasting test site near an industrial factory building in Zhongshan as an example,based on the finite difference software FLAC 3D,the numerical analysis method of the influence of blasting vibration on surrounding buildings is discussed.The simulation results show that the peak value of three-dimensional velocity of blasting vibration is Z direction>X direction>Y direction,the results of simulation calculation are consistent with the monitoring data in general,and the results of safety evaluation of the buildings around blasting by using numerical analysis method and field monitoring method are consistent,the research results can provide reference and reference for the safety evaluation of the buildings around the blasting construction in the future.
