Zusammenfassung:A new method is proposed for predicting an increase in shear strength of soft ground due to embankment construction. A proposed formula for this prediction was derived on the basis of the concept of critical state line in logƒ-logp plane. Only two parameters were used in the formula: the slope of logƒ-logp curve of the soil and compression strain of the soil stratum. This formula can be applicable for both normally consolidated soils and over consolidated soils including peat soils. Verification of the method showed good agreement between predicted shear strength and measured one.
