摘要
为了完成在复杂条件下控制爆破拆除大型钢筋混凝土地道的科研与施工任务,对爆破参数选取、孔网布置、药量的确定、起爆顺序、起爆网路、爆破危害及其防护等问题,分别进行了计算并提出了具体做法。
In order to fulfil the dismantlement of reinforced concrete pedestrian tunnel in Shenzhen Railway Station with controlled blasting under complicated conditions, blasting parameters are respectively calculated including hole pattern, charge weight, blasting sequence and blasting circuit. Such problems as blasting hazards and prevention are also considered in the paper.
