Session Start Date

5-6-1984

Abstract

Time and environmental constraints necessitated the development of unique methods for building earthen embankments over very deep and soft swamp deposits. Three case histories are presented. Construction techniques included alternate strip embankments, use of flexible vertical and horizontal drains, use of wood chips and high strength geotextile and the conventional stage and preloading techniques. In all cases, field instrumentation including pore-pressure/settlement transducers was installed to monitor the fill placement. The monitoring results were fed into a computer to determine the safety factor against shear failure and amount of settlement. The field monitoring results and predicted values agreed very well.
