Abstract

In order to find out the influences of the coefficient of permeability and the coefficient of consolidation on the consolidation of nonhomogeneous soils, self-developed program was used. For the purpose of analysis, nonhomogeneous soils of two layers which have various values of coefficient of permeability and coefficient of consolidation were assumed and analyzed by the developed program. According to the results obtained by the analysis, coefficient of consolidation has great effect on the distribution of excess pore water pressure and the consolidation settlement whereas coefficient of permeability has little effect on the characteristics of consolidation of nonhomogeneous soils.

불균질지반의 압밀에 미치는 투수계수와 압밀계수의 영향을 살펴보고자 해석목적에 맞게 자체적으로 코딩한 프로그램을 사용하였다. 두 개의 압밀층으로 구성된 해석대상지반에 대하여 투수계수와 압밀계수를 달리한 다양한 조건을 가정하여 압밀해석을 수행하였다. 해석결과에 따르면 불균질지반에서의 과잉간극수압분포 및 압밀침하량에 미치는 영향에 있어서는 압밀계수의 영향이 큼을 알 수 있었고 투수계수의 영향은 미미하였다.
