| 摘 要： | 中深孔光面爆破或预裂爆破质量对永久边坡的长期稳定性与安全性至关重要。利用偏心不耦合装药爆炸应力场的全息动光弹研究成果，对传统不耦合装药结构进行了改进，使高边坡光面爆破或预裂爆破效果得到明显改善，减少了因爆破效果不佳而造成悬、浮石滑落的事故隐患。并在实践中取得了一些有益的经验，可供同仁借鉴。

| Abstract: | Stress-field is studied by use of dynamic photo-elastic experiments in this paper. The results show that a charge pattern may have a significant effect on the distribution of the initial shock wave pressure on the hole wall.Such an initial pressure caused by an eccentric decouple charge will decrease with the increase of the distance between hole-wall and cartridge surface. According to the results the quality of smooth and pre-split blasting is improved through changing their patterns of decouple charges. |
