| 摘 要： | 针对宝兰二线马家磨车站高边坡扩堑的开挖厚度小的特点,采用浅孔弱松动小台阶控制爆破的施工方案,给出了相应的爆破参数、起爆顺序和防护技术措施.工程实践表明,按照该方案施工,能有效控制爆破飞石和震动效应,且爆堆集中;内侧炮孔先起爆可改变爆堆移动方向,避免爆碴向既有线一侧塌落. |

| Abstract: | In view of the construction characteristics of Ma Jiamou station in the second Bao-lan electric Railway, the project of the short-hole faint loose blasting with low bench was used in this paper. The corresponding blasting parameters, detonating order and defending measures are given. The engineering practice shows that the flyrocks and effect of seismic waves in blasting can effectively be controlled by applying the construction project. The muckpile is centralized, that the inside blasthole of blasting region is detonated before outside blasthole can change the motion direction of muckpile, which avoids the blasted fragments falling toward the existing railway. |
