CONSOLIDATION OF SATURATED SOIL, UPON ACTION OF EXTERNAL LOAD NORMAL TO BOUNDARY OF HALF-SPACE

IN THE THEORY OF TERZAGHI (1931), GERSEVANOV (1933), AND FLORIN (1959), THE WATER SATURATING THE SOIL PORES IS CONSIDERED TO BE INCOMPRESSIBLE AND THEREFORE WHEN AN EXTERNAL LOAD IS APPLIED TO THE SOIL THERE INSTANTANEOUSLY APPEARS IN THE WATER A CERTAIN INITIAL DISTRIBUTION OF THE PRESSURE. THIS PRESSURE CAUSES FILTRATION OF THE WATER TO EXTERNAL DRAINS AND CONSOLIDATION OF THE SOIL. UPON CONSOLIDATION OF THE SOIL THE PRESSURE IN THE WATER SATISFIES FOURIER'S EQUATION IN PARTIAL DERIVATIVES, THE INITIAL CONDITION AND THE BOUNDARY CONDITIONS IN THE PLANE IN WHICH THE LOAD IS APPLIED AND AT INFINITY. THIS PAPER CONTAINS THE SOLUTION OF THE PROBLEM OF SOIL CONSOLIDATION FOR THE CASE WHEN THERE IS DRAINAGE IN THE PLANE OF LOAD APPLICATION. SOLUTIONS HAVE BEEN OBTAINED FOR A LOAD APPLIED NORMALLY TO THE BOUNDARY OF THE HALF-SPACE AND UNIFORMLY DISTRIBUTED ALONG THE LENGTH OF A STRAIGHT LINE, A CIRCLE, AND THE AREA OF A CIRCLE. THE SOLUTIONS HAVE BEEN FOUND BY MEANS OF SUPERPOSITION OF POINT DIPOLES. THEY COVER CASES OF LOADS CHANGING IN TIME IN ACCORDANCE WITH A GRADUATED SCHEDULE, AS WELL AS THE CASE OF PERVIOUS SOIL WITH A FINITE LAYER THICKNESS. /LCPC/RRL/A/
