Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate


Ability to process real data and undertake specific calculations for the optimal choice of materials and sizing of the constructions through one Coursework covering the three sections (dams, tunnels and deep basements)
Knowledge and understanding of advanced design of geotechnical structures and skills in closed form solutions through a 2 hour unseen examination


Thus, the summative assessment for this module consists of:

·         Examination [Learning outcomes assessed 1, 2, 3, 4, 5] (2 hours) {60%}

·         Coursework [Learning outcomes assessed 5] (38 hours) {40%}

Formative assessment and feedback

Formative Feedback will also be given in tutorial sessions and after specific request using SurreyLearn.

Students will receive written feedback on the coursework as well as verbal feedback. 

Module aims

  • Explain the main aspects of engineering design of geotechnical stuctures (dams, tunnels and deep basements)
  • Study the conditons that may influence the design of geotechnical stuctures
  • Illustrate how to synthesize soil and material data for a design and define methodologies/techniques for soil and material characterization
  • Describe and study the causes and mechanisms of failure
  • Introduce robust computational methods for analysis (analytical and/or numerical approach)
  • Provide the ability to design and implement in situ investigation for detailed design
  • Provide the ability to plan the construction of geotechnical structutes and establish a program of monitoring
  • Explain criteria for observational approach

Lecture Hours: 30

Methods of Teaching / Learning

The learning and teaching strategy is designed to:


Improve the awareness and skills required for the design and analysis of geotechnics structures (dams, tunnels and deep basements), and will be delivered principally by lectures with tutorial/question classes.


The learning and teaching methods include:


Lectures and tutorials (30 hours)


Dams [Lectures (8 hours), tutorials (5 hours)]

Tunnels [Lectures (8 hours), tutorials (5 hours)]

Deep Basements [Lectures (2 hours), tutorials (2 hours)]


Directed and guided reading (78 hours)
Coursework writing (40 hours)


 

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
