Large-scale geotechnical analysis of new and aged pipeline infrastructure. This project aims to develop novel computational methods for predicting failure rates in geographically distributed pipeline networks affected by ground movements, one of the main triggers of bursts and leakages in buried pipe infrastructure.

This project aims to develop novel computational methods for predicting failure rates in geographically distributed pipeline networks affected by ground movements, one of the main triggers of bursts and leakages in buried pipe infrastructure. The project will be based on a blend of experimental work and development of simulation tools to quantify the coupled effects of pipe deterioration, poor backfilling and ground movements in aged and new pipelines. The results will feed towards the formulation of a framework for the large-scale stress analysis of segmented and continuous pipes, capable of using as input high-resolution geospatial observations and predictions of ground movements.Read moreRead less
Unsaturated soil-structure interaction with emphasis on buried pipelines. Buried pipeline networks is the most common mode of transporting and distributing water, oil and gas resources and pipeline failures may have a major socioeconomic and environmental impact. The goal is to develop a framework for describing the mechanisms underlying soil-pipe interaction, aiming to reduce the failure risk of pipes affected by geohazards. The project aims to model the response of pipelines in the laboratory, ....Unsaturated soil-structure interaction with emphasis on buried pipelines. Buried pipeline networks is the most common mode of transporting and distributing water, oil and gas resources and pipeline failures may have a major socioeconomic and environmental impact. The goal is to develop a framework for describing the mechanisms underlying soil-pipe interaction, aiming to reduce the failure risk of pipes affected by geohazards. The project aims to model the response of pipelines in the laboratory, using a new custom-built apparatus. Experimental results are expected to provide insight for developing a theoretical model to quantify the effect of soil moisture on pipe integrity, and propose design formulas. A general framework is intended to be developed for handling various unsaturated soil-structure interaction problems in geotechnical engineering.Read moreRead less
