ELASTIC-PLASTIC ANALYSIS OF COMPRESSIVE LOADED PILES

摘要: 1-INTRODUCTION: DESPITE OF DEVELOPING SOIL MECHANIC SCIENCE AND GEOTECHNICAL ENGINEERING IN THESE DECADES, THERE ARE MANY PROBLEMS FOR DETERMINING OF BEARING CAPACITY OF PILES. THESE PROBLEMS HAPPEN BECAUSE OF DIFFERENT PHYSICAL AND MECHANICAL PROPERTIES OF SOIL SUCH AS INHOMOGENEOUS, EXISTING WATER, COMPLICATED MANNER OF STRAIN-STRESS BETWEEN SOIL AND PILE, DIFFERENT TYPES OF SOILS AND DIFFERENT TYPE OF PILES. THEREFORE THESE COMPLICATED AND DIFFERENT CONDITIONS CAUSE TO THE MODELING OF PILES BECOMES HARD. BASED ON THIS, DIFFERENT RESEARCHERS HAVE SUGGESTED DIFFERENT SOLUTIONS FOR DETERMINATION OF PILES CAPACITY. MOST OF THE AVAILABLE METHODS FOR DETERMINING THE BEHAVIOR OF LOAD-SETTLEMENT OF PILES IN LAYERED AND HOMOGENEOUS SOILS ARE IN ELASTIC CONDITION. THE PURPOSE OF THIS PAPER IS THE PRESENTING A SIMPLE METHOD FOR CALCULATING THE BEARING CAPACITY OF PILES AND DRAWING THE LOAD-SETTLEMENT CURVE IN ELASTIC-PLASTIC CONDITION.
