摘要
以移动地表土与基础底接触界面的剪切变形特征试验为基础，研究了土体移动对基础底面的作用机理，明确了土体移动对基础底面的作用包括剪切与滑动两个过程；提出了土体与基础底面的联结单元的数学与力学模型．通过土体与上部砌体结构共同作用的有限元分析以及相应的模型试验结果比较，验证了所建立的单元模型的可靠性．
Based on the test results of shear deformation in the interface between soil and building foundation due to ground movement, the action mechanism of ground movement on the soil and foundation interface is studied. The action is divided into two phases of shear and slid. A model of the action for finite element analysis is presented. According to the comparison of analysis and test results for soil and brick masonry structure interaction, the reliability of the model is verified.
