Abstract

Nowadays more and more engineering structures are constructed on soft soils of low strength. High compressibility, low permeability and liability to secondary compression of these soils can result in long-term settlements and a menace with critical situations when the construction deadlines are tough. To cope with these problems several technologies have recently been developed in the embankment construction practice. Staged construction, over-filling, vertical drainage, stone columns, dynamic compaction — all of them often combined successfully with geosynthetics — are preferred to the previously predominant technology of soil replacement. Nevertheless, common design methods often do not balance properly the structural modeling, computation, economical and construction aspects. This is why a correct design may become a subject of reconsideration and modification in specific circumstances. There remains a room for innovative approaches, when conventional solutions are used. Two examples seem to prove that construction combined with monitoring may turn out to be good compromises.
