Centrifuge modelling of the effect of tunnelling on buried pipelines: mechanisms observed

Abstract

Ageing infrastructure such as pipelinesare often subjected to third party activities, such as tunnelling. If engineers are unable to confidently judge the effects on the pipeline in question, this may result in costly and possibly innecessary diversions to avoid the problem. Current methods of assessing the effect of tunnelling on buried pipelines are mostly based on elasticity and although extremely useful for parametric studies and preliminary evaluation of the problem, may contradict true behaviour. The aim of this paper is discuss the underlying mechanisms governing pipeline response to tunnelling based on results from centrifuge testing. LOKASI: Ruang Koleksi Umum Rak: 2
