| 摘 要： | 采煤沉降区面积较大或建筑平面面积较大时，建筑结构稳定性分析结果往往不准确，设计了一种新的采煤沉降区建筑结构稳定性分析方法。通过多源SAR数据融合，实现采煤沉降区的建筑地面监测，构建采煤沉降区的建筑结构有限元计算模型；通过有限元分析法实施建筑结构数值模拟，对建筑地基在建筑荷载作用下的土体空间实施受力分析，获取地基沉降和变形情况；通过模拟沉降区建筑结构应力场特征分析采煤沉降区的建筑结构稳定性。测试结果表明，设计方法的模拟准确度较高，且计算性能比较优越，能够满足设计需求。

| Abstract: | When the area of coal mining subsidence area is large or the plane area of buildings is large，the analysis results of building structure stability are often inaccurate.A new analysis method of building structure stability in coal mining subsidence area is designed.The building ground monitoring in coal mining subsidence area is realized by multi-source SAR data fusion.The finite element calculation model of building structure in coal mining subsidence area is constructed，and the numerical simulation of building structure is carried out by finite element analysis method.The stress analysis of the soil space of the building foundation under the building load is carried out to obtain the foundation settlement and deformation.The stability of building structure in coal mining subsidence area is analyzed by simulating the stress field characteristics of building structure in subsidence area.The test results show that the simulation accuracy of the design method is high，and the calculation performance is superior，which can meet the design requirements. |
