Abstract
The invention relates to a method and a test setup for determining the bearing behaviour of displacement piles. The displacement piles are produced by making a hole using a displacement head and subsequently filling the hole with a hardenable suspension, whilst leaving the displacement head in the hole. The resulting test pile is subject to the action of a test load using a loading device and the bearing behaviour is measured by a measuring device. An efficient test performance results from the fact that the displacement head is introduced into the ground by means of a metallic pile string, which forms part of the test pile.
