APPLICATION OF THE ELASTIC THEORY TO HIGHWAY EMBANKMENTS BY USE OF DIFFERENCE EQUATIONS /WITH DISCUSSION/

THE THEORY OF ELASTICITY IS USED TO DETERMINE SHEARING AND NORMAL STRESSES IN A TRAPEZOIDAL EMBANKMENT AND ITS FOUNDATION CONSISTING OF A RELATIVELY THIN, UNIFORM, NATURAL LAYER WHICH, IN TURN, IS UNDERLAID BY A RIGID BOUNDARY, SUCH AS THE TOP SURFACE OF A ROCK OR STIFF SOIL DEPOSIT. IT IS ASSUMED THAT THE MATERIALS OF THE EMBANKMENT AND ITS FOUNDATION ARE CHARACTERIZED BY IDENTICAL ELASTIC CONSTANTS. USING THE STRESS FUNCTION, A SERIES OF DIFFERENTIAL EQUATIONS IS OBTAINED AND REPLACED BY FINITE DIFFERENCE EQUATIONS FROM WHICH THE STRESSES MAY BE FOUND. THIS IS DONE FOR A NUMERICAL EXAMPLE IN WHICH MOHR'S CIRCLE IS APPLIED TO DETERMINE THE VALUES OF COHESION AND INTERNAL FRICTION REQUIRED TO PREVENT AN OVERSTRESSED CONDITION IN THE GIVEN STRUCTURE. /AUTHOR/
