摘　　要：风化岩体边坡的爆破开挖质量要求高,根据开挖边坡岩体条件,确定了合理的施工方案和爆破参数;为检验参数的合理性,结合爆破试验,进行了爆破振动效应的控制研究,并利用数字式全景钻孔摄像系统对开挖结果进行了评价。试验结果表明:采用的爆破方案可以满足边坡稳定性控制要求,爆破对岩体产生的损伤较小。试验成果可用于改善爆破施工效果、提高施工效率。The quality requirement of weathering rock slope excavation by blasting is higher.The optimal construction method and blasting parameters were determined according to the slope rock conditions.The blasting experiment was carried out to verify the rationality of the blasting parameters,and evaluated the experiment result with the digital bore panoramic camera system,which used to test the blasting result.The test results show that the blasting scheme can meet the slope stability control requirements,and less damage on rock mass,which give some help to improve the blasting results and improve the efficiency of construction.
