Title: COEFFICIENT OF EARTH PRESSURE AT REST AS RELATED TO SOIL PRECOMPRESSION RATIO AND LIQUID LIMIT
Accession Number: 00229917
Record Type: Component
Abstract: FROM EXPERIMENTS ON THREE TYPES OF SEATTLE CLAYS CONDUCTED IN A SPECIALLY DESIGNED STRESS METER, THE AUTHORS ESTABLISHED A RELATIONSHIP BETWEEN PRECOMPRESSION RATIO, PR, AND THE COEFFICIENT OF EARTH PRESSURE AT REST FOR OVERCONSOLIDATED SOILS WITH PR EQUAL TO OR LESS THAN 12. THIS RELATIONSHIP IS ALSO FOUND APPLICABLE TO SEVERAL SOIL TYPES TESTED BY OTHER RESEARCHERS. A UNIQUE RELATIONSHIP WAS OBSERVED BETWEEN THE COEFFICIENT OF EARTH PRESSURE AT REST FOR NORMALLY CONSOLIDATED SOILS AND THE LIQUID LIMIT OF THE SOILS TESTED BY THE AUTHORS AND OTHERS. A REDUCTION IN THE MAGNITUDE OF THE COEFFICIENT OF EARTH PRESSURE AT REST FOR OVERCONSOLIDATED SOILS AS A FUNCTION OF INCREASING DEPTH BELOW THE GROUND SURFACE IS INDICATED. ALSO, A RATIONALE FOR THE INCREASE OF THIS COEFFICIENT BECAUSE OF OVERCONSOLIDATION IS SUGGESTED. /AUTHOR/
