The Variation of Engineering Characteristics of Soft Ground with Construction Step of Vertical Drains

This study concerns with the variation of engineering characteristics of soft ground under embankment treated vertical drains. The derived engineering characteristics can be used in the prediction of increased strength of soft ground treated with vertical drains. The variations of physical properties such as liquid limit, natural water content, void ratio, and dry unit weight, and mechanical properties such as strength, preconsolidation ratio, compressibility are analysed and suggested. The co-relation of physical properties and mechanical properties with installation of vertical drains in soft ground are derived in this study.
