输供水工程隧洞爆破技术分析

Analysis on Tunnel Blasting Technology in Water Supply and Delivery Engineering

长距离水工隧洞的施工相对于普通隧洞而言,难度高、技术复杂、工程量大,常常采用钻爆法施工来开挖隧洞。为确保开挖过程安全的顺利实施及更加安全可靠地完成围岩凿除,结合隧洞的岩石特性及施工特点,通过全断面开挖的方法,对隧洞工程爆破技术及其过程进行重点分析,从而得出爆破施工过程中具体技术要求及爆破方法,为相似水利工程现场施工提供参考。

Compared with ordinary tunnels,the construction of long-distance hydraulic tunnels is difficult,technically complex,and has a large amount of engineering.Drilling and blasting is often used to excavate the tunnel.To ensure the safe and smooth implementation of the excavation process,it is more safely and reliably completed Surrounding rock excavation,combined with the rock characteristics and construction characteristics of the tunnel,through the full-section excavation method,focus on the blasting technology and process of the tunnel engineering,to obtain specific technical requirements and blasting methods in the blasting construction process Provide favorable reference for on-site construction of water conservancy projects.
