AN APPROXIMATE NON-LINEAR INVESTIGATION OF DEEP HIGHWAY CUTS

THIS PAPER IS CONCERNED WITH THE NONLINEAR ANALYSIS OF THE BEHAVIOR OF DEEP HIGHWAY CUTS SUCH AS THOSE ENCOUNTERED ON SEVERAL RECENT PROJECTS. TRILINEAR SOIL STRESS-STRAIN APPROXIMATIONS WERE UTILIZED IN CONJUNCTION WITH THE VERSATILE FINITE ELEMENT METHOD TO OBTAIN THE DESIRED SOLUTIONS. COMPUTER-GENERATED SHEARING STRESS AND DISPLACEMENT PLOTS WERE USED TO DEPICT ROAD-CUT BEHAVIOR GRAPHICALLY. INITIAL STRESSES, BUTTRESSING, SLOPE FLATTENING, AND SOIL VARIATION WERE CONSIDERED IN THE ANALYSES; CONCLUSIONS CONCERNING THE EFFECTS OF VARYING THESE PARAMETERS ARE PRESENTED. NONLINEAR ANALYSIS IS SHOWN TO BE QUITE SIGNIFICANT IN SOME CASES AND OF PRIME IMPORTANCE IN DENOTING PROGRESSIVE SLOPE FAILURE. PRACTICING ENGINEERS AND GEOLOGISTS SHOULD FIND THE RESULTS OF THIS INVESTIGATION TO BE OF INTEREST. /AUTHOR/
