CONSOLIDATION OF PEAT BY MEANS OF ATMOSPHERIC PRESSURE MEASURE

Geotechnical investigations had indicated that a portion of the new Yokohama freight line would traverse a drowned river valley consisting of very soft peat layers. Stability of the embankment and cost of suitable fill made necessary some sort of soil stabilization. Atmospheric pressure loading, a consolidation procedure developed in Sweden, was tested. For soft and weak soil deposite, it was found that this method had great effect, particularly in the upper fibrous peat which was extremely soft. It is concluded atmospheric pressure loading is widely adaptable and is not confined to any single soil type.
