摘要
本文采用最新的离散元 UDEC3 .0版本对锚拉支架支护散体顶板进行了数值模拟分析计算 ,研究了散体顶板的应力场 ,锚拉支架的锚杆的轴力和拉杆的拉力 ,顶板位移 ,拉杆的变形迹线 ,锚拉支架维护散体顶板的稳定情况等。
Numerical analysis of friable roof supported by truss is given in this paper by using DEM software UDEC. The stress field of friable roof, axial force of bolt and tensile force of pull rod, as well as roof displacement is measured. The paper also describes deformation trace and stability of friable roof maintained by truss.
