1-D Consolidation of Periodically Layered Soil

Abstract

A convenient and computationally efficient technique for analyzing the one-dimensional consolidation of periodically layered deposits is developed. This technique involves the use of a Laplace transform and an analytic solution to the governing equations is determined in transformed space. The transform is then inverted numerically. This technique requires minimal computational storage or calculation. The technique is then used to examine the response of periodically layered deposits. Particular emphasis is given to the effects of pumping from an underlying aquifer and to the time required to establish steady state flow from an overlying (possibly polluted) aquifer. The consolidation of deposits with a linear initial excess pore pressure distribution and impermeable or permeable base is also fly examined.
