FOUNDATION DESIGN OF EMBANKMENTS CONSTRUCTED ON CONNECTICUT VALLEY VARVED CLAYS
The report encompasses three main subjects. These are: (1) Presentation of a general methodology for the foundation design of embankments, especially regarding construction on soft ground; (2) A summary and synthesis of the engineering properties of Connecticut Valley varved clays, with emphasis on anisotropic strength, deformation and consolidation characteristics; and (3) Specific recommendations for the foundation design of embankments constructed on Connecticut Valley varved clays within Massachusetts. The last topic includes field and laboratory test programs; procedures for executing stability, deformation and consolidation analyses; the use of preloading with sand drains and surcharge fills; selection of soil parameters for design; and supervision of construction and evaluation of performance. Use of theoretical analyses and normalized soil properties are illustrated via an example design problem. Chapter 8 of the report presents a detailed summary of the design recommendations. /FHWA/
