Geotechnical Challenges- Balance between Risk & Opportunity

Geotechnical Challenges Balance between Risk & Opportunity
Geotechnical Challenges- Balance between Risk & Opportunity

Geotechnical engineering is often referred to as a black box because it deals with materials below the ground which are naturally variable in both properties and behaviour. This variability is often not well understood, which presents a significant risk and opportunity for both designers and contractors. As geotechnical engineering is not an exact science, the solutions to the same problem may be vastly different depending on the appetite for an aggressive or conservative solution.  In Jeff’s presentation, he will firstly talk about the behaviour of soil and rock, the uncertainties associated with such materials and the risk mitigation measures that can be adopted to achieve satisfactory geotechnical performance.


  He will then present several case histories where significant geotechnical challenges have been overcome by a balanced approach, taking into account both risks and opportunities.  These case studies include embankments constructed on soft soils, a cut & cover tunnel built in saturated loose sands, a TBM tunnel bored in karstic limestone formation and construction of an innovative two-staged reinforced soil wall to accommodate large ground settlement. Jeff’s presentation will demonstrate how a balanced approach can be used to reach an optimum geotechnical solution.
