Module overview

This module is designed to provide insights into aspects of advanced soil mechanics, which are necessary to carry out design of geotechnical structures and foundations.

Module aims

interest students in the deeper aspects of geotechnical engineering.

introduce the drained and undrained shear strenth of soils and its implicaiton for geotechnical design.

introduce stiffness of soils, in particular its nolinearity and anosotropy.

provide students with advanced understanding of the constitutive models of soils including critical state framework.

introduce the advanced soil testing methods for obtaining the design parameters

Module content

Indicative content includes:


Revision of basic soil mechanics


Index properties of soil, soil classification, charicterisation and testing, permeability, compressibility and consolidation, fundamental soil testing


Strength of soil


Effective stress concept, undrained strength of clay, drained strength of sand and clay (peak, residual, critical state)


Soil stiffness


Undrained/drained modulus, Young’s modulus, shear modulus, bulk modulus, strain level, stiffness variation against depth, anisotropy.


Constitutive models for soil


Basic FE in geotechnical engineering, stress paths, compression and swelling, normal compression line (NCL), critical state line (CSL), Mohr-Coulomb model, Cam-clay model, critical state framework


Advanced soil testing


Cyclic triaxial tests, dynamic simple shear, bender element test, resonant column test.


Site Investigation


Exloration and sampling, in-situ testing, interpretation of test data.

Methods of Teaching / Learning

The learning and teaching strategy is designed to:


cover advanced topics in geotechnical engineering in addition to the fundamental geotechnical engineering and soil mechanics found in undergraduate modules, and is delivered principally by lectures with tutorial/question classes.


The learning and teaching methods include:


Revision lectures/tutorials (4 hours)
Soil strength lectures/tutorials (4 hours)
Soil stiffness lectures/tutorials (4 hours)
Constitutive models lectures/tutorials (9 hours)
Advanced soil testing lectures/lab demonstration (6 hours)
Site investigation lectures/tutorials (3 hours)
Directed and guided reading (80 hours)
Coursework (38 hours)


 

Assessment Strategy

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


Knowledge and understanding of advanced aspect of soil behaviour, appropriate choice of stiffness in geotechnical design, and plan of experimental testing for attaining design parameters (LOs 1-5) are through a 2 hour unseen examination.



Ability to interpret advanced soil test data to obtain the design parameters (LO 5) is assessed through coursework.


Thus, the summative assessment for this module consists of:

·         Examination [Learning outcomes assessed 1, 2, 3, 4, 5] (2 hours) {80%}

·         Coursework: Process advanced soil test data provided; make appropriate selections for the design scenarios provided. [Learning outcomes assessed 5] (38 hours) {20%}

Formative assessment and feedback

Formative Feedback will also be given in tutorial sessions.

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