A New Strategy for Mitigating Pipeline Uplift in Liquefied Soils

Seismic-induced liquefaction is one of the main hazards for pipelines buried in saturated granular materials. When soil is partially or completely fluidized, a lifeline, although installed in superficial trenches in which the coarse backfill soil usually is compacted, may experience a sudden uplift and damages. To reduce pipeline uplift and...

Optimization of a District Heating Network with the focus on heat loss

In the Netherlands most houses and buildings are connected to a gas network since the nineteen seventies to heat our houses and cook. In march of this year the new Dutch government announced that to meet the climate accord of Paris all dutch household should be of the gas net in 2030. To do this multiple alternatives to heat homes are available...

Pipe uplift in liquefied sands: The case of induced earthquakes in the Groningen area

This study considers pipe uplift in liquefied sands in case full liquefaction occurs in the Groningen area. Due to the short vibration time, approximately 2 seconds, uplift is considered in fully liquefied sands without vibrations. The liquefaction time and resistance against uplift are determined by experiments. The resistance against uplift is...

Numerical Simulations of Full Scale Tests Investigating Effect of Fault Movement on Buried Pipeline

This master thesis investigates the response of buried pipelines under ground-induced deformations through the finite element simulations of a testing program undertaken at TU Delft Stevinlab II as part of the GIPIPE research project.
