Novel Application of Wet Deep Soil Mixing for Foundation of Modern Wind Turbines

Owing to good experience with the foundations of road bridges and heavily loaded footings supported on deep soil mixing (DSM) columns, some of them being in service for about 10 years, it has been considered to apply DSM technology for wind turbine foundations. Meanwhile, 33 such projects have been successfully completed in Poland since 2007. The adopted execution method and the design procedure, based on finite element method (FEM) 3D calculations, are outlined first, followed by two case histories illustrating the use of unreinforced and reinforced DSM columns, purposely located along the periphery of wind turbine foundation. In the first case a transition layer above the columns is required to avoid excessive tensile forces in soil-mix material. For reinforced columns bond stress of soil-mix must be checked to assure safe transfer of tensile loads to steel solider elements.
