ANALYSIS OF STRESS DISTRIBUTION UNDER EMBANKMENTS ON SOFT FOUNDATIONS

MODELS AND NUMBERICAL ANALYSIS WERE USED TO ANALYZE THE BEHAVIOR OF MUCK--MUCK BEING DEFINED AS A DEPOSIT OF SOFT CLAY OR ORGANIC SOIL. GUIDELINES WERE ESTABLISHED FOR PROTOTYPE STUDIES AND FOR DESIGN OF EMBANKMENTS AND LEEVEES, ETC. SEVERAL METHODS AND MATERIALS WERE STUDIED AS POSSIBLE MODELS REPRESENTING MUCK. IT WAS FOUND THAT GELATIN WAS THE MOST SUITABLE REPRESENTATIVE MATERIAL. A TECHNIQUE WAS DEVELOPED FOR THE CONSTRUCTION OF THE MODEL MUCK AND MODEL EMBANKMENTS. ALL DIMENSIONS WERE CHOSEN TO REPRESENT GEOMETRIC AND PHYSICAL CHARACTERISTICS OF PROTOTYPE MUCK AND ACTUAL EMBANKMENTS. EMBANKMENTS WITH AND WITHOUT BERMS WERE CONSTRUCTED IN TRENCHED AND UNTRENCHED SECTIONS. THE CONSTRUCTION SEQUENCES OF EMBANKMENTS (LOADING PATTERNS) WERE STUDIED AND VARIOUS TYPES OF EMBANKMENT MATERIAL (COHESIVE AND NON-COHESIVE) WERE USED TO DUPLICATE PROTOTYPE CONSTRUCTION AND MATERIAL CHARACTERISTICS. DISPLACEMENTS AND STRESSES DEVELOPED AND THE RESULTS WERE COMPARED WITH THE CLASSICAL BOUSSINESQ APPROACH. ALSO THE FEASIBILITY OF PRODUCING A NUMERICAL ANALYSIS APPROACH TO THE PROBLEM OF LARGE DISPLACEMENTS WAS STUDIED. A TECHNIQUE FOR ANALYZING THESE DEFLECTIONS WAS FOUND USING THE FINITE-ELEMENT METHOD. /AUTHOR/
