- Abstract:
- Row piles retaining structure will affect the settlement distribution of composite foundation for high—rise buildings．Based on this，by using finite element numerical simulation tools，a simple 3一D FEM model of the composite foundation considering the effects of row piles retaining structure is established．By usingdifferential settlement as control indicator and the change of the foundation deformation modulus to express thechanges of bearing stiffness，as well as considering the existence of row piles retaining structure，the distribu—tive regularity of settlement curve is discussed when we use the design method for composite foundation consid—ering of the space—varying rigidity．Research shows that the settlement distribution is obviously affected by rowpiles retaining structure．Hence based on the control of differential settlement，when we use the design methodfor foundation considering of the space—varying rigidity，we should consider the effect of row piles retainingstructure．Research results possess a certain theoretical guidance on reducing the side-piles that locate themarginal part of raft，reducing differential settlement，and ameliorating hypo—stress of the raft and superstructure．
