摘要
以DK80+230~DK80+306段路堑石方开挖施工为背景,研究石方开挖施工邻近高压线爆破情况下的爆破方案的选择及施工经验总结,论文结合工程实际情况,详细描述路堑控制爆破石方开挖中依据不同地质情况下,深孔及浅孔爆破方式的选择,单位炸药消耗用量、炮孔直接选择、钻孔深度、炮孔间距及排距、布孔方式、堵塞长度、单孔装药量、起爆顺序等各项参数的计算依据及安全防护措施、施工操作要点、施工注意事项等,为类似工程的施工起到一定的借鉴。
Based on the background of the excavation construction of DK80+230~DK80+306 section of cutting,studies the selection of blasting scheme and construction experience summary in the case of blasting of high-voltage lines adjacent to stone excavation construction.The calculation basis of various parameters such as the initiation sequence,safety protection measures,construction operation points,construction precautions,etc.,play a certain reference for the construction of similar projects.
