Deep foundations

UNIT 1. BASIC CONCEPTS AND COLUMN PILES IN SOILS Types of deep foundations. Terms. General rules of a deep foundation design Bearing capacity of a pile in soils: Basic formulation End bearing capacity in granular soils through analytical solutions End bearing capacity in cohesive soils through analytical solutions End bearing capacity in soils. In situ tests UNIT 2. FLOATING PILES IN SOILS, PILES IN ROCK AND PILE GROUPS Skin friction capacity in granular soils through analytical solutions Skin friction capacity in cohesive soils through analytical solutions Skin friction capacity in granular and cohesive soils through in situ test Bearing capacity of a pile rocks Bearing capacity of a group of pile UNIT 3. WORKLOADS AND PILES SETTLEMENT Safety coefficient: single pile and group of piles effect Structural strength Settlements in deep foundations Uplift load Dynamic formule for pile driving UNIT 4. PILE SELECTION AND UNUSUAL SITUATIONS Verifying safety against ground failure owing to horizontal pull or pressure Negative Friction in Piles Load test in piles Choosing the type of pile Micro-piles
