By expounding on some typical examples of design and implementation of soft soil improvement works with prefabricated drains,discussions are made on the selection of coefficients of consolidation in the design of soft soil improvement works,the anisotropic characteristics of the coefficients of consolidation,the method for calculating the final settlement by way of measured settlement curves and the depth of soil improvement.Empirical methods for selection of the coefficient of consolidation during the design of soft soil improvement works are proposed on the basis of the back-analysis of the field measured data and the statistical analysis of the laboratory results.The problem of depth of improvement is discusse and the influence of construction factors upon the consolidation of soil is analyzed.
