摘要
针对煤矿采空区地面框架结构建筑物 ,利用有限元法对模拟动态开采过程中的地表移动变形所产生的框架附加内力进行计算 ,分析了框架附加内力与地表移动变形之间的关系和附加内力的分布规律 。
In this paper,on the basis of ground movement and deformation obtained from simulation tests of dynamic mining process,additional internal forces of a reinforced concrete frame structural building on the ground surface over goaves are calculated with finite element method;distribution features of additional internal forces and the relationship between ground movement and deformation are analysed;the effect of additional internal forces on the safety of buildings is also discussed.
