| 摘 要： | 本文采用有限元与边界元耦合方法对上与结构物进行共同作用的分析．其中上部结构采用有限元子结构法，地基上考虑为横观各向同性特性，应用边界元法，通过基础界面上位移连续、面力平衡的条件进行耦合分析．编制了相应的计算程序，对某高层空间剪力培与地基的共同作用进行了计算，与有限元法和实测结果进行了对比分析，得到了满意的结果．说明：有限元和边界元的耦合方法能充分发挥两者的优越性，不失为共同作用分析的一种有效途径．

| Abstract: | Based on the potential theory, a boundary element method for 3D transverse isotropic soil medium is developed for the analysis of interaction between structure and soil (transverse isotropic) by coupling of FEM with BEM. A typical interaction between tall spatial shear wall structure and soil is analyzed. The numerical results are shown to be in good agreement with the measured data and results by FEM. |
