摘　　要：在路堑石方开挖中，由于周围存在建筑物和构筑物，爆破施工环境复杂，有时不能按照常规爆破设计施工，为使爆破施工安全可靠，满足工程质量，在具体施工中根据起爆先后改变抵抗线的大小和方向，用以控制飞石和振动强度．工程实践表明，所提出的变抵抗爆破技术安全可靠，可获得满意的爆破效果．In Cutting excavation, because of buidings and structures around it, the blasting operations borne more difficult, sometimes construction can't even carry out awarding to routine blasting design. In order to meeting the requirements of blasting safety and engineering quality, the teChnology of altering resistance line diredn and she based on blasting sequenre can be used for controlling flying-rocks and vibratinn intensity. Some engineering practics have indicated that the satisfied blasting results can be obtained using this technology.
