Aspects of the Joint Operation of a Ring Foundation and a Soil Bed with Zones of Inhomogeneity Present

摘要

Maximum allowable tank bed settlement values are determined with due regard for structural steel metalwork stiffness when an inhomogeneous zone is present in the bed. A Drucker-Prager model for linear elastic-plastic materials is used in the article to simulate an inhomogeneous zone, and is implemented in the ANSYS finite-element model program package.
