摘要
文中对采动区地表变形的成因及状况作了简要的阐述。通过分析轻钢结构门式刚架建筑物在采动地表移动和变形作用下的内力、位移反应，得出了门式刚架各种保护措施抵抗地表变形的效果，对在采动区兴建轻钢门式刚架结构建筑物有一定的指导意义。
A brief introduction is made in the paper to cause and condition of surface deformation in mining-induced area. By analyzing internal force and displacement variation of portal rigid-framed buildings with lightweight steel construction under the effect of mining-induced surface displacement and defo-mation, the effect of various protective measures taken to portal rigid-framed buildings against surface displacement is obtained, which provides instructive significance to a cert-in degree to build portal rigid-framed buildings with lightw-ight steel construction in mining-induced area.
