the report describes a computer program, written in the fortran iv language, for predicting the relation between settlement and time during one-dimensional consolidation of multi-layered soils. the program permits the analysis of settlement with stratified soils where up to twenty layers with different properties are present and can also take account of variation of the soil parameters during the consolidation rpocess. both instantaneous and multi-stage forms of construction loading can be treated by the program. the accuracy of the solutions obtained by using the computer program have been confirmed by comparisons with available solutions to several problems of consolidation. the program was used for analysing the rate of consolidation of multi-layered soils at two road embankment sites. a comparison of the predicted and measured vertical distributions of excess porewater pressure at various stages of consolidation at these two sites show good agreement (a).
