LATERAL STABILITY OF RIGID POLES PARTIALLY EMBEDDED IN SAND

FUNCTIONAL RELATIONSHIPS ARE DEVELOPED FOR THE LOAD- DEFLECTION CHARACTERISTICS OF A RIGID, VERTICAL POLE, EMBEDDED IN SAND AND SUBJECTED TO A HORIZONTAL LOAD APPLIED ABOVE THE GROUND LINE. 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, APPLIED FORCE, MOMENT ARM, TIME OF LOADING, AND SOIL PARAMETERS. INTERNAL FRICTION, FLOW CHARACTERISTICS, AND RELATIVE DENSITY OF THE SAND. NONDIMENSIONAL TECHNIQUES IN CONJUNCTION WITH SMALL-SCALE MODEL STUDIES ARE USED TO DETERMINE THE EXPLICIT FORM OF THE INTERRELATIONSHIP AMONG THE PRECEDING PHYSICAL VARIABLES FOR A POLE EMBEDDED IN A VERY DENSE, UNIFORM, FINE DUNE SAND OF CONSTANT PROPERTIES AND SUBJECTED TO AN APPLIED HORIZONTAL FORCE. HYPERBOLIC PREDICTION EQUATIONS ARE GIVEN FROM WHICH THE LOAD- DEFLECTION CHARACTERISTICS OF A PROTOTYPE POLE MIGHT BE ESTIMATED. THE SUPERPOSITION OF GROUND-LINE COUPLE AND GROUND-LINE THRUST RELATIONSHIPS TO REPRESENT THE MORE GENERAL CASE OF A HORIZONTAL LOAD APPLIED ABOVE THE GROUND LINE IS INVESTIGATED. THE RESULTS OF THE PRESENT FORMULATION ARE COMPARED WITH BOTH MODEL AND FIELD STUDIES REPORTED BY OTHER INVESTIGATORS. /AUTHOR/
