摘要
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 mechanical models for the system of fractured roof and truss, the numerical solution of stability is studied with the deformation of blocks along diagonal direction and horizontal direction at support. The stability of curves, namely the stability of balance route in the movement of roof structure is analyzed. The static bifurcation behaviour of the system is discussed. The mechanism of instability in the movement of roof structures is also analyzed, and the conditions of stability in the movement of the system are given.
