Abstract
This paper develops a coupled region method,which divided the entire foundation system into near region(cap,pile group,soil)and far region.Considering the characteristics of geometry,material, and load in each region,they are modelled by semi analytical finite element method and semi analytical boundary element method respectively. By considering continuity conditions on the interfaces,the equations with respect to all unknowns can be set up and worked out.The small amount of computation work,simple data preparation, and high accuracy of the present method can be demonstrated by analysing some examples.
