摘要
通过对拉林铁路布喀木隧道横洞掘进采用光面水压爆破技术,经过试验数据对比分析,指出隧道Ⅱ,Ⅲ级围岩光面水压爆破技术能节省炸药用量、加快施工进度、提高经济效益、增强降尘效果,实现长大隧道Ⅱ,Ⅲ级围岩的快速掘进。
In this paper,the smooth surface water pressure blasting technique is used to excavate the cross tunnel of Bukamu tunnel in Lalin railway,comparative analysis of test data,the smooth surface blasting technology of classⅡ,Ⅲsurrounding rock of tunnel can effectively improve the energy utilization ratio of explosives,speed up the progress of construction,improve economic benefit,improving the operating environment,the fast excavation of classⅡandⅢsurrounding rock of long and long tunnel is realized.
