An important consideration when planning and carrying out tunnelling works is the impact that those works may have on Third Party assets, particularly in cities. Damaging ground movements and loads may be caused by the tunnelling itself and/or by associated works for shafts.
The impacts of tunnelling on buildings throughout the world have been widely reported but the impacts on utility apparatus have not received such detailed and extensive attention in the literature. The principal purpose of this lecture is to consider strategies and methods of impact assessment for utility pipelines and tunnels. he content is informed by numerous investigations into pipeline failures and consideration of the geo-environment of pipelines in cities which may render conventional analyses unreliable or even intractable.
The lecture will discuss the current, mainly analytical, approaches to the problem and suggest other more broadly risk based methods which may be considered for future application. The emphasis will be on simplifying the assessment process to reflect the uncertain condition of the pipelines and other relevant factors but retain the asset protection essential to utility providers.
Speaker: Dr Barry New, Geotechnical Consulting Group.
