综放工作面端头区弧形板形成的力学机理分析

摘要

通过建立工作面顶板的力学模型,分析了工作面顶板内的应力分布规律,以及工作面端头区弧形三角板的形成过程,验证了工作面端头弧形三角板客观存在的事实,并结合虚位移原理及工程实例,论述了弧形三角板形成的条件,为类似问题的研究提供参考.%In this paper,by establishing the mechanical model of roof,analyze the stress distribution inside the roof of working face,and arc tri-angle formation process in the working face end zone,verify the objective facts of the working face end arc triangle,combined with the virtual dis-placement principle and engineering examples to analyze of the formation of arc triangle,provided reference for similar problem research.
