摘　　要：根据煤矿老采空区地表移动变形规律 ,利用ANSYS软件模拟计算了老采空区“活化”引起的地表变形对门式刚架结构产生的内力影响。通过分析数值计算结果 ,研究了轻钢结构整体变形的特点及其不同部位受附加内力作用的情况。Based on the regularity of the foundation movement deformation over the abandoned mine goaf,a numerical model of the steel portal frame is set up. The internal force in steel protal frame caused by the ground deformation is simulated using the ANSYS software. According to the results of numerical simulation,the integrally deformational ability and the additional internal force in different parts of the frame are analyzed.The calculating method of additional internal force is presented.The effective construction protection measures are developed to enhance the integrally anti-deformational ability of the steel structure buildings.
