本文基于工作经验,分析了在高速公路工程建设中,石方路堑开挖的施工质量控制和爆破施工安全管理中的工作难点,针对存在的超爆、超震、超(欠)挖现象,运用预裂(光面)综合爆破技术,对这些现象进行了有效的预防和控制,合理的减少了扰动,保证了路堑边坡的整齐和稳定,为石方爆破施工提供了可以借鉴的经验和做法。
Based on the working experience, this paper analyzes the construction quality control and the safety management of blasting during the construction of expressway construction. In view of the existing phenomenon of over-blast, over-shock and over-under-excavation, The pre-cracking (smooth) comprehensive blasting technology effectively prevents and controls these phenomena, reduces the disturbance rationally and ensures the tidiness and stability of the cutting slope, providing experiences and practices for the blasting construction of stonework .
