摘要

本文根据对预裂爆破震动效应的测试结果,研究了边坡工程中预裂爆破震动波的传播特点和规律,对预裂爆破的减震效果进行了分析,分别考虑主爆孔到预裂面的距离、预裂孔的单响药量和单孔药量、预裂孔与主爆孔之间起爆时差等方面提出了降低预裂爆破震动强度的措施,同时得出了一些有益于最优化预裂爆破设计的结论。
According to the measurement result of pre-splitting blasting vibration effects in the slope engineering in this paper,the transmitting characteristics and law of the pre-splitting blasting vibration wave are investigated. The effect of shock-absorption in the pre-splitting blasting is analyzed. The measures of reducing the pre-splitting blasting seismic intensity are proposed considering the distance of pre-splitting face,the single hole dose,one delay interval doses of pre-splitting hole,and the initiation time difference between pre-splitting holes and the main blasting holes etc. Some beneficial conclusions on the optimum design of are summarized which are available for reference to practical projects.
