摘　　要：提出了两种改进的光面爆破边坡开挖方法。通过对孔壁压力与不偶合系数的关系分析和模型试验结果证明,改进方法开挖效果明显优于传统方法,并具有推广使用的价值。Two methods of slope excavation of improved smooth blasting were proposed in this paper, excavation results of improved smooth blasting is obviously superior to the traditional method by indication of results of model experiment and analysis of connection of borehole presure and decoupling coefficient, and which has some values to popularize.
