摘　　要：基于有限元模型,对采空区顶板覆岩的抗震变形稳定性进行了分析,通过水平和竖直方向不同地震波峰值的输入,得到岩体中最大位移的发生位置及加速度的分布规律,为采空区上方覆岩与地表建筑相互影响的研究提供了理论依据。Based on the finite element model,the paper undertakes the seismic deformation and stability analysis of the roof in goaf,and concludes the locations of the maximal displacement of the rock and the distribution of the accelerator according to the input of the various seismic wave peak in the horizontal and vertical directions,so as to provide some theoretic reference for studying the mutual influence between the roof cover and ground buildings at the goaf.
