几种典型爆破振动控制技术的试验研究

为有效控制爆破施工过程中所产生的爆破地震效应，分别开展了电子雷管起爆、加减振孔、加空气垫层、不同起爆方向等典型爆破振动控制技术的减振试验研究，得到了质点振动速度、减振率、振动衰减系数等典型振动参量的变化规律.试验结果表明，各减振技术在相应条件下均能起到一定的减振效果，实际工程爆破施工时，应综合考虑爆区地质条件和周围环境因素，选择合适的爆破振动控制技术. 

Experimental Research on Several Typical Blasting Vibration-Controlling Technologies

To effectively control the blasting seismic effect produced during blasting construction,different vibration reduction tests of some typical blasting vibration controlling technologies,including electronic detonator initiating,damping hole method,air cushion method and different initiating directions,were carried out.The change law of typical vibration parameters such as particle vibration velocity,vibration reduction ratio and vibration attenuation coefficient were obtained.Results show that these vibration reduction technologies can produce a certain damping effect under corresponding conditions.In the actual engineering blasting construction,geological conditions and surrounding environmental factors should be considered and the appropriate blasting vibration controlling technology should be chosen.
