FUNCTIONAL RELATIONSHIPS ARE DEVELOPED FOR THE LOAD- DEFLECTION CHARACTERISTICS OF RIGID, VERTICAL POLES, EMBEDDED IN SAND, SUBJECTED TO A HORIZONTAL GROUND-LINE THRUST AND GROUND-LINE COUPLE-MOMENT. THE STUDY IS BASED ON NONDIMENSIONAL TECHNIQUES AND THE PHYSICAL VARIABLES INCLUDED IN THE THEORETICAL ANALYSIS ARE THE GROUND-LINE DEFLECTION, DEPTH OF EMBEDMENT, GEOMETRY OF THE POLE CROSS- SECTION, GROUND-LINE THRUST, COUPLE-MOMENT AT THE GROUND- LINE, TIME OF LOADING, AND SOIL PARAMETERS. THE SOIL PARAMETERS USED ARE THE DENSITY, ANGLE OF INTERNAL FRICTION, AND FLOW VISCOSITY OF SAND. NONDIMENSIONAL TECHNIQUES IN CONJUNCTION WITH SMALL-SCALE MODEL STUDIES ARE USED TO DETERMINE THE INTERRELATIONSHIP AMONG THESE PHYSICAL VARIABLES FOR A POLE EMBEDDED IN A DENSE, UNIFORM, FINE DUNE SAND OF CONSTANT PROPERTIES AND SUBJECTED TO A HORIZONTAL GROUND-LINE THRUST ONLY. PREDICTION EQUATIONS ARE GIVEN FROM WHICH THE LOAD-DEFLECTION CHARACTERISTICS OF A PROTOTYPE POLE MIGHT BE DETERMINED. A FAILURE CRITERION RELATING THE ULTIMATE GROUND-LINE THRUST TO THE POLE GEOMETRY AND EXAMPLES ARE GIVEN. /AUTHOR/
