A study on the one-dimensional consolidation of double-layered structured soils

摘要

The governing equations for the one-dimensional consolidation of double-layered structured soils under time-dependent loading are established in this paper. Using simplified k-sigma' and m(v)-sigma' models, the double-layered structured soils can be analyzed with three- or four-layered soils in which the thicknesses of the upper and lower layers change gradually. Approximate solutions for the governing equations are then obtained for two types of boundary conditions, and a computer program is developed. Using these solutions and the computer program, the consolidation behavior of double-layered structured soils is investigated. (C) 2015 Elsevier Ltd. All rights reserved.
