在以前工作的基础上，对同时考虑块体沿对角线变形和沿支应处的水平变形两个因素引起的稳定性问题进行了初步的数值求解；讨论了解曲线即平衡路径的稳定性及系统的静态分叉特征；分析了层状断裂顶板锚拉支架系统的运动失稳机制，并给出了该系统的运动稳定条件。
Based on the previous work, the stability problem caused by the two factors including the diagonal deformation of the block and the horizontal deformation along the branch is considered. The stability of the equilibrium curve and the stability of the system The static bifurcation characteristics of the system are analyzed. The mechanism of the instability of the anchoring system of the layered fracture roof is analyzed and the motion stability conditions of the system are also given.
