摘要
本文用厚板力学的方法,研究了坚硬顶板采场薄板力学解的可行区域作出了实用的工程判断图,并导出了四种边界条件板的厚化系数表达式,对必须用厚板来解的顶板,用相同边界条件的薄板解乘以厚化系数,即得厚板的解。
By means of thick plate mechanics, the paper deals with the applicable range of thin plate mechanics soluion in hard roof of working face, gives the practical charts for engineering judgement and derives, the expresstns of thickening coifficients for four boundary conditions of plates. The thick plate solution may be obtained by the product of the thin plate sotution and thickening coifficient at similar boundary condition.
