| Abstract: |
Vertical columns are commonly used for the construction of embankments over soft soils to reduce the settlement and improve the stability of embankments. The vertical columns are designed to improve the bearing capacity of the soft soil and to transfer the load of the embankment through the soft compressible soil layer to a firm foundation. To support the load transfer from the soft soil into the stiff columns, especially if the layer thickness above the columns is small, geocell reinforced load transfer platforms above the columns can be used. The paper describes the general application of geocell reinforced load transfer platforms and measurement results from construction site in Germany, where the system was installed for the first time. |
