摘　　要：通过对含软弱夹层的边坡岩体模型爆破试验,研究最小抵抗线、装药量和装药位置等因素对软弱夹层爆破层裂效应的影响规律,进而提出控制顺层边坡岩体爆破层裂效应的技术措施,以防止含软弱夹层的顺层边坡岩体因爆破层裂作用而产生顺层滑坡事故。Taking blasting tests of slope rock mass with weak intcrlayer＇s model and studying the factors such as minimum burden, charge and sausages location and so on which affect blasting bedding cracks of weak interlayer. And then come up with the technology methods to control bedding cracks in bedding slope rock mass blasting. So that bedding landslide accident can be prevented because of blasting bedding cracks in bedding slope rock mass with weak interlayer.

关 键 词：爆破试验 软弱夹层 顺层边坡 层裂效应 控制措施
