Analysis of the Impact of Blasting Vibration on Small Distance Tunnels and Optimization of Construction Methods
In order to reduce the impact of blasting vibration on the lining structure of small clearance tunnels,improve construction efficiency and safety,this article first introduces the engineering overview,and then uses two-dimensional and three-dimensional finite element methods to analyze the transverse and longitudinal effects of blasting vibration on the lining of small clearance tunnels.The research results indicate that blasting vibration produces significant stress fluctuations on the lining structure,and the smaller the net distance,the more significant the impact.Based on this,this article proposes targeted optimization measures for construction methods,including adjusting blasting parameters,optimizing excavation sequence,etc.These optimization strategies aim to effectively control the impact of blasting vibration and provide scientific basis and technical support for the construction of small clearance tunnels.
