Settlement evaluation of spread foundations on heavily preconsolidated cohesive soils

摘要

Settlement evaluation of spreadfoundations on heavily preconsolidated cohesive soils. The paper presents the results of field and laboratory tests performed on the heavily preconsolidated boulder clays which prevail on the campus of the Warsaw University of Life Sciences - SGGW as foundation layers. Based on the results of field and laboratory tests a problem of spatial variability assessment of the thickness of foundation layers and the soil parameters is discussed. Special attention is drawn to theselection of the design values of oedometer moduli and the suitability of calculation methods for settlement evaluation. Calculated settlements were approved by the field measurements performed during building construction.
