中文摘要：

爆破含软弱夹层的边坡岩体时，夹层充填物在爆炸气体的冲刷、推移和压密等作用下沿夹层高速运动并形成夹层空腔，从而降低边坡岩体的稳定性。介绍含层间充填土的混凝土模型爆破实验，用高速摄相机拍摄层间充填土在爆破作用下的运动过程，分析了最小抵抗线对夹层土运动速度影响规律。

英文摘要：

In blasting of slope rock mass with weak intercalation,interlayer filled soil moves at a high speed a- long weak intercalation and engenders cavity in degradation, driving and compression of blasting gas. It can reduce stabihty of slope rock mass. Blasting tests of concrete model involving interlayer filled soil is introduced in this pa- per. Motion process of interlayer fill soil in blasting effect is shot by high speed camera system. Effect laws of burden motion speed of weak intercalation were analyzed.
