Deep Foundations

UNIT 1. BASIC CONCEPTS AND COLUMN PILES IN SOILS Types of deep foundations. Terminology. General rules for deep foundation design Bearing capacity of a pile in soils: Basic formulation End bearing capacity in granular soils using analytical solutions End bearing capacity in cohesive soils using 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 using analytical solutions Skin friction capacity in cohesive soils using analytical solutions Skin friction capacity in granular and cohesive soils through in-situ tests Bearing capacity of piles in rock Bearing capacity of a group of piles UNIT 3. LOADS AND PILE SETTLEMENT Safety factor: effects of single piles and groups of piles Structural strength Settlements in deep foundations Uplift load Dynamic formula for pile driving UNIT 4. PILE SELECTION AND UNUSUAL SITUATIONS Verifying safety against ground failure due to horizontal pull or pressure Negative friction in piles Load testing of piles Selecting the type of pile Micropiles
