ES95C - Rock Mechanics

Module Leader: Professor Tony Price

BTS Champion: Sotiris Psomas, Associate, Morgan Sindall Underground Professional Services

(15 Credits)


Aims : This module aims to:

Provide the theoretical background to the practical task of ensuring the underground excavation is accurately positioned. This involves controls for setting out and monitoring excavation progression. Consideration is also given to the prediction and monitoring of surface displacement above underground openings which forms an important restriction on urban sub-surface works.

Learning Outcomes: At completion, students will be able to:

  • Apply a knowledge of rock mechanics to a range of rock engineering applications, in both the design and the monitoring of post-excavation performance.
  • Predict the behaviour of the rock mass in response to excavation.
  • Interpret rock mass classification data to formulate support strategies
Syllabus: Overview:
  • Behaviour of jointed rock mass (structure): Shear behaviour of discontinuities. Shear testing techniques. Compressibility of rock masses. Insitu testing of rocks.
  • Rock excavation design and assessment: Behaviour of rock around underground openings: ground condition, index properties, insitu measurement of stress and strain, elastic and elasto-plastic behaviour, rock bursts and stress problems, effects of groundwater.
  • Rock mass classification systems.
  • Design of surface excavations.
  • Use of stereographic techniques.
