Abstract
Pressure-grouted piles are recently more and more often used instead of anchors as bracings for sheet pile walls. In Germany, the piles are mostly tested in the same way as anchors, i. e. according to DIN 4125. The load-deformation behaviour of pressure-grouted piles and anchors in sand during load testing and in the final state is investigated and compared. First, the different systems of both elements are described and the regulations according to the current standards are presented. Then calculation results obtained with the finite element method are presented. With respect to the final state, pressure-grouted piles show in usual load tests a significantly different, i. e. more favourable behaviour. The main reason for that is that in the load test, in contrast to the final state, anchor forces can be transferred to the soil inside the active sliding wedge. This effect is even enforced by a restraint between wall and soil due to the propping of the hydraulic jack for the test load against the wall. These effects must be considered in the evaluation of load test results with pressure-grouted piles.
