M5 CONCEPTS

Question 1

• Fundamental concept in soil mechanics that deals with stress distribution and settlement in an elastic half-space subjected to a concentrated load at the surface.
• The theory provides a way to calculate the stress and displacement fields around the point load

Answer 1

Boussinesq Theory

Question 2

Assumptions of Boussinesq Theory

Answer 2

1) homogeneous
2) isotropic
3) linearly elastic
4) load is concentrated/ point load

Question 3

Types of Settlement

Answer 3

1. Uniform Settlement
2. Tipping Settlement
3. Differential Settlement

Question 4

Components of Settlement

Takes place during or immediately after the construction

Answer 4

Elastic or immediate settlement

Question 5

Components of Settlement

• Occurs over time
• Pore water is extruded from the void spaces causing settlement

Answer 5

Consolidation Settlement

Question 6

Two Phases of Consolidation Settlement

Answer 6

1. Primary Consolidation
2. Secondary Consolidation
