SETTLEMENT AND STABILITY OF EMBANKMENTS CONSTRUCTED ON SOFT ALLUVIAL SOILS

This paper describes the results of an extensive programme of research into the problem of predicting the magnitude and rate of settlement of embankments constructed on compressible subsoils. Field measurements have been obtained from a number of sites. These results have been compared with predictions based on conventional consolidation theory and on a multi-layer analysis using compressibility parameters determined from measurements of the in situ permeability of the subsoil. The problem of stability control is also considered and an approach which has been developed and used successfully at several sites is described. A brief outline is given of some construction expedients for countering problems of settlement and stability and an assessment is made of the cost effectiveness of drainage consolidation techniques.
