《岩土力学》2010年第8期刊登了“动力扰动诱发承压底板关键层失稳的突变理论研究”一文[1](以下称为原文),原文的分析模型引用文献[2],认为对于长壁全陷采煤工作面,可以假设底板隔水带是四边固支的矩形平板[2]。隔水底板上部受已破坏的底板导水裂隙带的重力Fr作用,下部受均布水压力Fw作用;平板边界受水平力H、剪应力N和 “Rock and Soil Mechanics” 2010 the 8th published a “dynamic disturbance induced stress floor instability of the critical layer of the theory of mutagenesis” [1] (hereinafter referred to as the original), the original text of the analysis model reference [2] , That for the longwall coal mining face, it can be assumed that the floor barrier is a rectangular plate fixed on both sides [2]. The upper part of the water-proof bottom plate is affected by the gravity Fr of the damaged water-carrying fracture zone of the bottom plate, and the lower part is affected by the uniform water pressure Fw; the boundary of the plate is affected by the horizontal force H, the shear stress N and
