摘　　要：基于弹性地基梁理论,采用局部弹性地基模型,对软土地基上框架结构柱下条形基础在平面荷载下各点的内力和变形进行了分析计算。并通过有限元计算软件SAP2000不同单元划分以及JCCAD对该柱下条形基础进行数值模拟,对比了不同计算方法间计算结果的差异。结果表明:数值模拟可以较好的模拟弹性地基梁的受力状态和变形,其计算结果满足工程要求。As the elastic foundation beam method can reflect the interaction of structure and soil, and effectively take into account the influence of different foundation conditions on the structural internal force and deformation, based on the theory of beam on elastic foundation, using local elastic foundation model, the internal force and deformation was calculated for the foundation of a soft soil foundation under the plane load. And through the finite element software SAP2000 division of different units and JCCAD numerical simulation of the strip foundation under column, the calculation results of different methods were compared. Results show that, numerical simulation results of the stress and deformation of the beam on elastic foundation is favorable with eligible calculation accuracy.
