THEORETICAL STUDY OF LATERAL REACTION MECHANISM OF PILES

The mechanism of the lateral reaction of piles in an elastic-plastic medium is examined. Plane strain is first assumed. The analytical solution for a circular section in an elastic medium is given. The influence of pile section (square pile), disturbance of a soil ring around the pile, plastic yield of soil in undrained behaviour (Tresca's criterion) are studied by means of the finite element method. All these factors affect strains and stresses only in the vicinity of the pile. Graphs are given making it possible to calculate the corresponding corrective terms to be applied to the analytical solution. In a second step, which defines the value of the outside radius of this two-dimensional model, the simplified three-dimensional problem of a horizontally-loaded vertical axis in a semi-infinite elastic solid is studied using Mindlin's Solution for a point force. The influence of the relative soil-pile rigidity, head loading and fixing conditions, which have an effect especially on distant fields, are taken into account and quantified by simple rules for determining this outside radius. Finally, a specific numerical application of the results is made and the solution is very satisfactorily compared with experimental measurements. /Author/TRRL/
