文章通过介绍断裂损伤力学中裂纹扩展阻裂理论,分析边坡在施加预应力锚索前后,边坡的安全系数变化情况及滑动面变动.通过abaqus软件建立二维边坡模型,通过对比发现,预应力施加以后,增加了形成新裂纹表面的表面能和裂纹推进过程中的形变能,使得裂纹不易继续发展,表明预应力锚索阻止裂纹在初始滑动面的开展效果是十分显著的.

Article by introducing the fracture damage mechanics crack propagation crack resistance theory, the slope before and after the prestressed anchor cable safety factor changes and changes in the sliding surface . ABAQUS software to create a two-dimensional slope model , by comparison, prestressing , an increase of the deformation energy of the surface to form a new crack surface and crack promote the process so that the crack is not easy to continue to develop , indicate that the prestressed anchor cable to prevent cracks carried out in the initial sliding surface effect is very signifcant .
