数码电子雷管在复杂环境下隧道爆破中的应用

Application of digital electronic detonator in tunnel blasting in complicated environment

以青岛地铁1号线四线断面隧道工程为依托,针对复杂敏感环境下爆破开挖施工,对施工重难点进行了分析,然后从数码电子雷管爆破网路、爆破参数、装药结构、爆破器材等方面对爆破施工技术措施进行了研究。最后采用MATLAB拟合萨道夫斯基公式,得到青岛硬岩条件下的爆破振动预测公式。从爆破效果来看,研究成果与结论取得较好地应用,并取得较好的社会效益和经济效益。

Based on the fourth-line cross-section tunnel project of Qingdao Metro Line 1,this article analyzes the major and difficult points of construction for blasting excavation in complex and sensitive environments,and then analyzes the digital electronic detonator blasting network,blasting parameters,charge structure,blasting equipment and other aspects introduced research on blasting construction technology measures.Finally,MATLAB is used to fit the Sadowski formula to obtain the blasting vibration prediction formula under Qingdao hard rock conditions.From the perspective of blasting effects,the research results and conclusions have been applied well,and good social and economic benefits have been achieved.
