挠曲褶皱性巷道底臌机理分析及防治对策研究

摘要

A catastophe model is put forward for analyzing destabilizingmechanism of flexible and folded floor. The zoning of floor stability in control space, influence of the force motion ways in control space on floor stability and the trigger mechanism of vertical force disturbance are probed. The ample and essential condition of deciding destabilizing is set up. On the basis of analyzing the effect of various affecting factors on floor stability, the control countermeasure of this kind of floor lift is also studied by means of FLAC.%提出了挠曲褶皱性巷道底板失稳机理分析的突变模型，探讨了底板稳定性在控制空间的分区、力在控制空间中的运动途径对底板稳定性的影响以及底板失稳的垂直力振动触发机制，建立了判别其失稳的充要力学条件。在分析各影响因素对底板稳定性影响的基础上，采用FLAC模拟，研究了挠曲褶皱性巷道底臌的防治对策。
