Finite Strain Consolidation for Vertical Drains

by R. Robert Goughnour, (A.M.ASCE), Geotechnics America, Inc, Peachtree City, United States,



Document Type: Proceeding Paper

Part of: Vertical and Horizontal Deformations of Foundations and Embankments

Abstract:

Consolidation equations for vertical prefabricated drains which consider finite vertical strain of the soil are derived. Estimated consolidation times are shorter when finite soil strain is considered, and this effect becomes greater as the strain becomes greater. A method of proportioning composite drains used for lateral drainage is proposed.
