陕北黄土岩石地层隧道爆破技术

Tunnel Blasting Technology for Loess Rock Stratum in Northern Shaanxi

隧道掘进爆破设计为隧道钻爆法施工技术研究的重点内容之一,对施工安全、进度、经济性均起到关键作用。结合陕北黄土岩石地层特殊地质特性,通过针对性设计,得出相对合理的参数及工艺,通过实践验证满足施工需要,可为类似工程施工提供依据。

Tunneling blasting design is one of the key contents of tunnel drilling and blasting construction technology research, and it plays a key role in construction safety, schedule and economy. Combined with the special geological characteristics of the loess rock stratum in northern Shaanxi, through the targeted design, the relatively reasonable parameters and processes are obtained, which can be verified by practice to meet the construction needs and can provide a basis for similar engineering construction.
