Educational Aim

This class aims to aims to give an introduction to the governing principles of geotechnical engineering, in particular stress and

settlement analysis and groundwater flow

Learning Outcomes

On completion of the class the student is expected to be able to

LO1 Understand mechanisms underlying water flow in the ground and predict pore-water pressures under steady-state flowconditionsLO2 Understand the concept of effective stress in saturated soils and characterise the soil stress state resulting from hydraulic

and mechanical loadingLO3 Understand mechanisms underlying soil consolidation and predict pore-water pressures/settlements under transientconditionsLO4 Understand water flow and consolidation laboratory testing and be able to derive soil parameters

Syllabus

The class will teach the following:

Topic 1: Water flow in soils.- Occurrence of water in soils Darcy’s law for water flow- The permeability of soils and permeability tests.- Water flow theory (homogenous media)- Introduction to flow nets and vector calculus revision- Water flow in heterogeneous media- Uplift pressure and critical hydraulic gradient

Assessment of Learning Outcomes

Criteria

For each of the Class Learning Outcomes the following criteria will be used to make judgements on student learning:

[Note: Criteria break the LO down into ‘teachable’ elements but do not become syllabus orientated i.e. no mention of CAD

package names, components etc.]

LO1 Understand mechanisms underlying water flow in the ground and predict pore-water pressures understeady-state flow conditionsC1 Calculate hydraulic conductivity from laboratory 1-D testsC2 Draw hydraulic head and pore water pressure profiles under 1-D flow in layered soilC3 Draw 2-D flow net in homogenous soil and calculate flow rate and pore-water pressures

LO2 Understand the concept of effective stress in saturated soils and characterise the soil stress state resulting

from hydraulic and mechanical loadingC1 Calculate effective stress profiles under static water conditionsC2 Calculate effective stress profiles under steady-state flow conditions

LO3 Understand mechanisms underlying soil consolidation and predict pore-water pressures/settlements undertransient conditionsC1 Calculate pore-water pressure time evolution in consolidating clay depositC2 Calculate degree of consolidation of clay depositC3 Calculate consolidation and final settlements

LO4 Water flow and consolidation testingC1 Determine hydraulic conductivity from 1-D flow testingC2 Determine hydraulic conductivity from field test methodsC3 Determine consolidation coefficient from oedometer testingC4 Determine 1-D compressibility from oedometer testing

The standards set for each criterion per Class Learning Outcome to achieve a pass grade are indicated on the

assessment sheet for all assessment.

12 Principles of Assessment and Feedback(on Learning & Teaching web pages: www.strath.ac.uk/learnteach/teaching/staff/assessfeedback/12principles/ )

Please state briefly how these are incorporated in this class.

3 Deliver high quality feedback information that helps learners self-correct.Feedback is provided in real-time in an interactive fashion. Students are asked to solve problems of different level ofcomplexity during the lecture and the lecture is tuned to the gaps shown by the students

4 Provide opportunities to close any gap between current and desired performance.Exam simulation is carried out during the term

7 Facilitate the development of self-assessment and reflection in trainingIn tutorials sessions, students are asked to become teachers by explaining tasks
