I9.~4 A mathemaucal analysis of the beha',iour ot dri',en piles ~s presented. The movement of each area of the pile is calculated for a gi,,en impact and information on stresses, deformations and veioci'~es ts obtained. Results calculated using the PILDYN program are compared v, ith those of model tests. 863265 Foundation problems of Tisza bridges Roz~-.

When narrov, foundations are subjected to horizontal loading. eff,.-cts may be seen in parts of the surrounding soil which were not considered in analysis of direct ',ertical loading of the :,tructure. Soil rupture bulbs and the corresponding volumetric stress distribution have been anal~,sed for horizontal loading. The resuhs ba'.c been confirmed by model tests on a variety of l'oundation shapes.
