The current chinese foundation design code gbj7 - 89 use limit equilibrium theoiy with elastic soil stress distribution to give out bearing capacity design value calculating fonnula and use elastic soil model to evaluate foundation settlement. according to the above theories, code gbj7 - 89 gives the correlative terms. but these do not accord with the practical mechanism of loaded soil below the shallow foundation and the elastoplastic property of natural soil so defects exist

Abstract : compared with soil destroyed pattern of vertical force and its controlled factor of bearing capacity, it is concluded that pile capacity and its tip resistence have some difference when soil with the same physical mecanic property is used as natural foundation and pile tip resistent layer. whereas the middle weathering rod stratum hasn ' t this property, that is to say it has the same bearing capacity and pile tip resistence
