RESEARCH HAS BEEN INITIATED TO DETERMINE THE NATURE OF THE INTERACTION BETWEEN A VEHICLE'S TRACTION ELEMENTS AND A YIELDING SOIL. IN ONE PHASE OF THIS WORK, PRESSURE-SENSITIVE CELLS WERE EMBEDDED IN SOFT SOILS TO MEASURE STRESS INTENSITIES INDUCED BY VEHICLES MOVING ON THE SURFACE OF THAT MASS. THE WORK IS COMPLICATED BY PROBLEMS OF SOIL HOMOGENEITY, INSTRUMENT RELIABILITY, AND DATA INTERPRETATION, AND BY SOIL FLOW THAT RESULTS IN DISPLACEMENT OF THE CELLS. MEASUREMENTS HAVE BEEN MADE IN SOIL BENEATH A PNEUMATIC TIRE, A RIGID WHEEL, AND TWO TYPES OF CRAWLER TRACKS. RESULTS, ALTHOUGH CHIEFLY QUALITATIVE, PROVIDE SOME INSIGHT INTO THE MANNER IN WHICH VEHICLE STRESSES ARE TRANSMITTED TO SOFT SOILS. /AUTHOR/
