摘要
应用弹塑性力学及断裂力学的相关理论 ,分析讨论了裂纹的分形特性及裂隙面的压剪起裂破坏机理 ;分析了静载、动载和不同类型裂隙的相互作用对边坡稳定性的影响规律 .结合工程实际问题 ,研究了边坡开挖前后其应力应变的分布规律 ,提出了由于开挖卸荷而引起裂纹扩展的作用机理 .
Based on elasticplastic mechanics and fracture mechanics theory, the fractal fissure and joint growth of the slope rock under compression and shear is discussed,and the interaction mechanism of static load and dynamic load on different cracks is presented. The distribution regulation of stress and strain in rock slope before and after digging are described, and the crack growth and propagation mechanism under the action of unloading is given.
