喀斯特地貌综合管廊爆破施工关键技术

Key Blasting Construction Technology of Pipe Gallery in Karst Landform

喀斯特地貌因其地质情况复杂,且占地面积极广,是管廊建设的一个重点研究课题。喀斯特地貌以岩层为主,内部溶洞、节理发育,兼有泥夹石情况,爆破施工难度大。以六盘水市地下综合管廊为例,系统分析了喀斯特地貌区域爆破的难点,研究喀斯特地貌的爆破施工技术。

The karst landform is an important research subject of pipe gallery construction because of its geological condition and extremely broad area. The karst landform takes the rock layer primarily, the internal limestone cave and jointing growth, the putty to clamp the stone situation, the blast working difficulty is big. Based on Liupanshui underground pipe gallery project construction, this paper analyzed difficulties in blasting and studied the blasting technology.
