## Course handbook

### Description

This is a first course in Geomechanics devoted to soil index properties, stress, seepage and deformation. It introduces the concepts of porous granular materials, total and effective stress, pore pressure and excess pore pressure, stress distributions in elastic materials, elastic deformation consolidation and time-dependent settlement.

### Availability

#### BCA Singapore

• Semester 2 - 2022

#### Callaghan

• Semester 2 - 2022

### Learning outcomes

On successful completion of the course students will be able to:

1. Quantify important physical characteristics of partially saturated and saturated porous materials from basic measured data.

2. Identify/estimate important soil properties and describe and classify soils according to AS1726.

3. Recall and describe common laboratory tests in soil mechanics and analyse data from these tests to determine quantities of interest.

4. Determine the total stress, pore pressure and effective stress in the ground, under both hydrostatic and steady-state seepage conditions.

5. Estimate steady-state seepage rates using flow net theory.

6. Estimate the stress distribution in the ground due to a range of spatially-discrete surface loadings.

7. Calculate primary settlements and rates of settlement in coarse and fine grained soils using appropriate theories.

8. Recognise that soil strength contains two components (cohesion, friction).

9. Explain which strength component applies to granular soils and cohesive soils for different loading and time scenarios.
