Abstract: The load, foundation flexure, vertical rigidity of upper structure, influence of foundation flexure on upper structure, adjustment of subgrade reaction and whole structural moment etc were expounded. A simplified calculated method of interaction between upper structure and foundation soil is advanced, which can really reflecte rigidity of upper structure and condition of geological formation.
Keywords: foundation flexure; vertical rigidity of structure;  additional intemal force;  subgrade reaction;  whole moment
