摘要
路堑开挖爆破上方有 2 2 0kV超高压输电线和电气化线 ,临近建筑物 ,对爆破振动和飞石控制严格 ,爆破设计和施工难度较大。介绍了复杂环境下路堑开挖控制爆破设计和安全技术。
As 220kV ultrahigh voltage transmission lines, electrified lines and some nearby buildings are existed above the cutting excavation blasting area, the restriction of blasting vibration and flying rocks are strictly required and the design and construction of blasting are very difficult as well. The paper introduces the design and safety techniques for cutting excavation controlled blasting, which can be used as a reference for the similar engineerings.
