水平层状红砂岩隧道掘进爆破振动效应研究

当前,国内外学者对近间距隧道爆破振动的相互影响问题进行研究,但是对于层状岩体中近间距隧道爆破开挖的动态响应问题的研究成果不多,缺乏针对性和系统性。依托吉怀高速公路大林隧道工程项目,研究水平层状红砂岩隧道掘进爆破过程中的震动效应、传播规律以及爆破地震效应对隧道超欠挖的影响,优化光爆参数,取得了很好的光爆效果。

On Blasting Vibration Effects of Horizontal Layered Red Sandstone Tunneling

At present,the interaction of blasting vibration between short interval tunnels are researched by scholars at home and abroad,but the research results of dynamic responses of blasting excavation between short interval tunnels in layered rocks are rarely seen,which lack directions and systems.In light of the Dalin Tunnel project in Ji-Huai Expressway,this paper studies the vibration effects and transmitting rules during the blasting process of horizontal layered red sandstone tunneling,as well as the blastin...
