摘要
介绍了紧邻皖赣铁路的高边坡路基开挖爆破施工方案,深孔结合浅孔台阶微差爆破开挖路基,选取了合理的爆破参数和防护措施,保证了爆破施工质量和既有线路的安全运营。可以为类似施工提供参考。
blasting construction scheme of high side slope excavation near Anhui-Jianxi railway is introduced in this paper. Roadbed is excavated by long-hole step millisecond delay blasting combined with short-hole. Reasonable blasting parameters and protective measures are chosen, which ensures the quality of blasting construction and the safety operation of existing railway line. This project can provide reference for similar construction.
