Abstract: A summary of the various techniques available to calculate downdrag forces on pile groups is presented. In light of all these existing techniques, a simplified method is recommended. An example is worked out to compare the results obtained with each method. Experimental data is presented and the results of a numerical simulation are highlighted.
