摘　　要：本文针对矿山采动区砖砌体房屋的特点,建立了考虑地基与上部结构协同工作的三维有限元模型。文中给出了墙体、地基及滑动层等单元的破坏模式及处理方法。数值模拟分析及现场试验表明,三维有限元模型能够反映采动区砖砌体房屋的受力状态,理论分析与实测结果基本一致。According to the features of brick masonry structures in mining ground subsidence areas and with consideration of the interaction between soil foundation and superstructure, in this paper a three dimensional finite element model for brick masonry buildings is set up. The failure hypotheses and handling methods of brick masonry, soil foundation and slip layer are given. Model analyses and spot tests show that the three dimensional finite element model can correctly simulate the stress state of brick masonry structures subjected to mining ground deformation, and the theoretical analyses are basically consistent with the test results.
