Abstract

Design of embankment constructed on soft ground has been conducted considering with the improved soil strength due to reinforcement use or consolidation. From a view point of construction, a practical safety factor includes some safety margin to adopt geotechnical materials satisfied with design strength. Geomaterial properties have highly variable so that the design parameter in safe side has been often adopted in practice. This paper describes the safety margin defined by a difference of safety factors in design and construction. This paper also reports the embankment stability during construction considering with the safety margins of used geosynthetic strength and improved soil strength due to consolidation.
