变强度混凝土夹层切裂爆破

Cut-crack Blasting of Concrete Layer for Different Strength

根据爆炸应力波理论和断裂面成缝机理，应用大不偶合装药系数与导向孔，有效地控制爆破裂隙的发展方向和断裂范围，成功地爆破了不同强度结构中的混凝土夹层。

According to stress wave theory. and cracking priciple ofsection, it efficiently controll developing direction and rupturingrange of blasting cracks that incoupling coeffi cient and guiding hole is used. It is a succese to blast hight strength concrete tayer in different strength construction.
