SOIL STRENGTH PREDICTION BY USE OF SOIL ANALOGS

THE CURRENT STUDIES OF SOIL STRENGTH PREDICTION BY THE LAND LOCOMOTION LABORATORY ARE IN SUPPLEMENT TO THE OVERALL STUDY OF TERRAIN ANALOGS. MANY STUDIES IN TERRAIN CLASSIFICATION PRECEDE THIS PAPER, SOME OF WHICH ARE LISTED IN THE BIBLIOGRAPHY. SEVERAL METHODS OF PREDICTING SOIL STRENGTH WERE INVESTIGATED BY SHORT TERM STUDY. THE STUDY WHICH SEEMED AT THE TIME TO OFFER THE GREATEST PROBABILITY OF SUCCESS PROPOSED THE ESTABLISHMENT OF SOIL ANALOGS. THE SOIL ANALOGS WILL BE ESTABLISHED BY USING THE UNITED STATES DEPARTMENT OF AGRICULTURE (USDA) SOIL CLASSIFICATION SYSTEM BY WHICH A MAJOR PORTION OF THE UNITED STATES HAS BEEN SAMPLED AND MAPPED. IN ORDER TO IMPLEMENT THE PROPOSED APPROACH, SOILS IN OTHER AREAS OF THE WORLD MUST BE CLASSIFIED IN TERMS OF THE USDA SYSTEM. WORK TO THIS END HAS BEEN IN PROGRESS FOR A NUMBER OF YEARS BY THE WORLD SOIL GEOGRAPHY UNIT IN HYATTSVILLE, MARYLAND. THIS SYSTEM OF SOIL CLASSIFICATION GIVES THE BROADEST DESCRIPTION OF SOIL PROPERTIES AVAILABLE. IT CONSIDERS THE PROPERTIES OF A SOIL MASS, IN SITU, AND DESCRIBES EACH SOIL HORIZON TO A CONSIDERABLE DEPTH BELOW THE SURFACE. ALSO CONSIDERED IS THE NATURAL VEGETATION, GROUND WATER, SLOPES, CLIMATE, AND MANY ADDITIONAL FACETS THAT ARE LACKING IN OTHER TAXONOMIC SYSTEMS. AN ADDITIONAL INPUT TO THE CLASSIFICATIONS IS THE WORK OF THE BUREAU OF PUBLIC ROADS IN FURNISHING THE UNIFIED SOIL CLASSIFICATION SYSTEM (USCS) AND THE AMERICAN ASSOCIATION OF STATE HIGHWAY OFFICES (AASHO) DESIGNATIONS FOR ALL MAJOR SOIL SERIES. DETERMINATION IS MADE AS TO WHETHER THE USDA SYSTEM LENDS ITSELF TO SOIL STRENGTH PARAMETERS.
