摘要
介绍了在路基高边坡爆破开挖中,应用炮孔复合装药结构技术,有效地控制了炸药爆轰波传播方向,降低了爆破冲击波及反射拉应力对高边坡保留岩体的作用,确保了高边坡的完整性和稳定性,并使保留岩面基本达到设计坡率的平整度。
In the practice of highway slope blasting, a compound charge structural technology, was used to effectively control the direction of propagation of shock waves, to protect the reserved rock mass of highwall slope from the destructive effect of the blasting, to insure the integrality and stability of the highwall slope, and to make the reserve scar according with the smoothness of the design ration of slope.
