ANALYSIS OF PILES IN SOIL UNDERGOING LATERAL MOVEMENT

The discussers observe that the author of the paper has made a good contribution to the analysis of horizontal pressures on piles due to causes other than those directly transmitted by the structures they support. The authors of the study (which is a comprehensive theoretical analysis on the topic in which soil-pile interaction due to external surcharge or any other horizontal movements producing cause is taken into account), base their calculation on the assumptions of Mindlin's solution for the soil-pile interaction and previous definition of the horizontal movement law if there was no pile. The method utilized is based on elastic hypothesis and posterior application of a yielding criteria. The pile is divided into strips where the soil reactions are constant. The discusser describes similar work using the integral equation that governs the problem which establishes the compatibility of soil and pile movements. This equation, however, is valid only under elastic conditions. Boussinesq's and Mindlin's solutions are discussed. Theoretical elastic solutions are compared with experimental field tests. Observations are made by the discusser concerning the author's analytical methods, the condition for soil yielding, the differences between numerical computation and the actual behavior, the use of limit values, the calculation of forces in the pile, and the maximum bending moment.
