ABSTRACT
For the realization of the high-speed railway in Belgium screw piles are often used in different kinds of applications such as foundation piles, ground improvement piles and in retaining walls. The piles are installed in different kinds of soft soils and often take important charges. Different design methods lead to a wide range of theoretical bearing capacities. To verify the bearing capacity of the piles axial loading tests have been performed. Based on the results of those tests a design method has been elaborated.
