ON CORRECT INTERPRETATION OF OBJECT INFLUENCE ZONES IN FINITE-ELEMENT GEOMECHANICAL MODELS

摘要

To account for the mutual influence of objects in finite-element geomechanical models, it is proposed to limit the deformation computation zone and adjust accordingly the settlement of the object, ground surface, and neighboring objects located in the influence zone. The boundary of the influence zone is represented by an isoline (isosurface) selected so that the additional vertical pressure from the erected structure in the deepest point of such zone does not exceed 10% of its initial value.
