摘要
隧道爆破产生的空气冲击波不仅会危害隧道内作业人员和施工机械的安全,还会影响围岩和衬砌结构的稳定性。合理控制空气冲击波的产生与传播是保证隧道爆破施工安全的重要一环。本文围绕隧道钻爆冲击波传播规律与控制技术,综述了近年来国内外在隧道爆破空气冲击波的传播规律、危害效应、预测方法和控制措施几个方面的研究进展。对几个典型的空气冲击波超压预测公式的预测精准度进行了比选,分析了不同公式的适用范围。从隧道空气冲击波超压预测方法、空气冲击波演化规律研究、空气冲击波主动防治装置等方面对隧道空气冲击波研究趋势做了展望。
The air shock wave generated by tunnel blasting will not only endanger the safety of workers and construction machinery in the tunnel,but also affect the stability of surrounding rock and lining structure.Reasonable control of the generation and propagation of air shock wave is important to ensure the safety of tunnel blasting construction.This article summarizes the research progress on the propagation regularities,harmful effects,prediction methods,and control measures of air shock waves in tunnel blasting in recent years,focusing on the propagation law and control technology of tunnel drilling and blasting shock waves.Several representative air shock wave overpressure prediction formulas were selected,the prediction accuracy of different formulas under different blasting conditions was calculated,and the applicable conditions of different formulas were analyzed.The research trend of tunnel air shock wave is prospected from the aspects of tunnel air shock wave overpressure prediction method,air shock wave evolution law research and air shock wave active prevention and control device.
