Numerical Investigation on Performance of Expanded Polystyrene Geofoam Block in Protecting Buried Lifeline Structures
Abstract—Expanded polystyrene (EPS) geofoam is often used in below ground applications in geotechnical engineering. A most recent configuration system implemented in roadways to protect lifelines such as buried pipes, electrical cables and culvert systems could be consisted of two EPS geofoam blocks, “posts” placed on each side of the structure, an EPS block capping, “beam” put atop two posts, ...

متن کاملTesting of Buried Pipelines Using Guided Waves
Introduction The inspection requirements of pipes that have an operational history of many tens of years have lead to the adoption of new maintenance practices and safety standards. The solution currently considered as best maintenance practice is the direct assessment of 100% of the pipelines with the minimum possible economical impact. The use of RBI (Risk Based Inspection) methods and the in...
متن کاملDetection of Bending Stresses in Buried Pipelines
When gas or oil pipelines must be laid through sand or permafrost or other unstable soils, the pipe walls can he subjected to large bending loads if the soil shifts. In order to detect this condition and correct it, it would be useful to monitor the state of stress along the pipeline'at regular time intervals using a vehicle that is moved through the line by the fluid or gas in it. The experime...
متن کاملRefinement to the Existing Analytical Methods of Analysis of Buried Pipelines due to Strike-Slip Faulting
Analytical methods presented to analyze the buried steel pipelines at strike-slip fault crossing use the Euler-Bernoulli beam theory. The cross-section of a buried pipe that is completely surrounded by soil cannot rotate freely and would not be remained perpendicular to the bending line after deformation. So it would be better to take into consideration a rotation between the cross-section and ...
