控制爆破技术在坪汉高速高陡边坡危岩体处理的应用

Application of Controlled Blasting Technology in the Treatment of High and Steep Slope in Pinghan Highway Slope

危岩危害极大,是公路、公路交通建设大发展的重要制约因素。陕西坪汉高速公路某隧道出口存在危岩,威胁安全为此,针对高陡边坡危岩体所处的特殊复杂环境,采用控制爆破技术及安全防护措施,以确保处理后的边坡满足公路运营期间的稳定与安全。

The dangerous rock is very harmful, which is an important restriction factor for the development of highway and construction. There is dangerous rock and threaten safety for a tunnel exit on Pinghanhighway in Shaanxi. Therefore, aiming at the special complex environment of high steep slope dangerousrock, controlled blasting technology and safety protection measures are adopted to ensure that the treatedslope meets the stability and safety during highway operation.
