Abstract:

In this paper,by taking the superstructure rigidity into consideration,a semi-analytical and semi-nume-ileal solution to the interaction between grillage beam foundation and subsoil is obtained based on the elastic beam theory and the Boussingesq solution. In the process of working out the solution,the grillage foundation on elastic subsoil is regarded as a composite system of beams in two directions. The superstructure is simplified as a plate with equivalent rigidity,and the force and the displacement among beams,slabs,columns and the gmund are compati-bly analyzed. It is proved by numerical examples that the proposed method is of high precision with less unknown data and it is convenient for practical engineering.

Key words: grillage beam, foundation, subsoil, interaction, semi-analytical and semi-numerical solution
