| Abstract: | 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. |
| Keywords: | stability bifurcation behaviour fractured roof truss |
