Abstract

Non-linear finite strain consolidation theory is used to predict the settlement of fine-grained dredged material due to self-weight and surcharge-induced consolidation. Finite strain consolidation theory accounts for the effects of (a) self-weight consolidation, (b) changes in permeability with consolidation, (c) a non-linear void ratio-effective stress relationship, and (d) large strains. An empirical desiccation model is used to describe the removal of water from confined dredged material by surface drying. The combined model has been coded into the microcomputer program PCDDF89 (Primary Consolidation, and Desiccation of Dredged Fill), which is also described. The Craney Island Dredged Material Management Area near Norfolk, Virginia is used to illustrate the use and accuracy of the model. The use of vertical strip drains to increase storage capacity of disposal facilities is also described.
