Abstract

China ranks as the third-largest country in terms of the distribution area of perennial frozen rock in the world. Perennial frozen rock poses a significant constraint on ground transportation extending to high-altitude or high-latitude frigid regions. This paper takes the blasting construction at the entrance section of a tunnel in a high-altitude cold region as the engineering context. According to the grade of surrounding rock and the size and shape of the tunnel section, reasonable blast hole layout and blasting parameters are designed. Surface measurement points are arranged near the tunnel entrance section to collect and analyze blasting vibration monitoring data, studying the propagation patterns of blasting vibrations. The results indicate that a total explosive amount of 157.5kg is required for a single blasting at the tunnel entrance section. The empirical formula for the propagation and attenuation of blasting vibration velocity in the entrance section of a frozen rock tunnel is:  V = 157.2 × ( Q 1 / 3 / R ) 1.54 . The research results of this article can provide experience for similar frozen rock tunnel construction.
