摘要
根据京福高速公路徐州绕城西段路堑爆破开挖的工程实际情况,在路堑爆破开挖中采用微差爆破和光面爆破技术相结合的V形掏槽一次成型中深孔双壁路堑爆破方法,爆堆均匀,光爆轮廓清晰,爆破效果好。
On the basis of the actual fact through blasting works for the Jingfu highway,once-through shaping in medium and deep hole twin slope-cut excavation blasting are used.The applications of combining the long-hole millisecond blasting and the smooth face demolition in this construction engineering are imtroduced.
