摘　　要：地基不均匀沉降是引起建筑工程事故的主要原因之一。利用有限元软件ABAQUS,分析地基沉降对上部框架结构的影响。分析固定支承和弹性支承条件下,柱1相对沉降量不同时上部结构的内力、变形,结果表明,支承条件不同、相对沉降量不同,上部结构的受力和变形有不同的变化规律,并验证了用弹性支承模拟的合理性,得出了一些结论,为将来类似的工程提供借鉴。Ground unequal settlement of building is a major cause of accidents. Using the finite elementsoftware ABAQUS to investigating the influence of the ground settlement on the frame structure. Analysis the structure＇s internal forces and deformation when column 1 appears different relative settlements under the fixed bearing and the elastic support,the results show that different support conditions and differentrelative settlement,the stress and the deformation of the upper structure has a different variation,the re-sults also verify the reasonableness of the elastic support. Some conclusions would offer reference for simi-lar projects.
