ANALYTICAL SOLUTION FOR 2-DIMENSIONAL DYNAMIC CONSOLIDATION IN FREQUENCY-DOMAIN

An analytical solution to the two-dimensional wave propagation in flui d-saturated half-space subjected to a strip load with vertical harmoni c oscillation at the surface is presented. The basic equations have be en derived on the basis of Blot's linear theory of pore-elasticity and then solved using Fourier complex transform for the horizontal direct ion. The importance of a number of soil characteristics including comp ressibility, degree of saturation and soil permeability has been exami ned. It is shown that the effect of pore fluid is dominant only for fu lly saturated soils with incompressible solid grains and low permeabil ity. For partially saturated, compressible or very permeable soils, th e stresses would be mainly transferred to solid part and there will be considerable reduction in pore pressure amplitude.
