Performance Study of Buried Pipelines under Static Loads

The possibility of servicing lifelines such as highways, railways, pipelines, and tunnels is great social importance. characteristic that separates the buried pipeline from other structures its dimensions are very long compared to dimensions. Ground vibrations caused by earthquakes, construction activities, traffic, explosions, machinery can damage these structures. Lifeline integrity be compromised in two ways: (1) direct due excessive dynamic loading lifeline, (2) indirect soil failures liquefaction, slope instability, differential settlements. 3D printing (also known additive manufacturing) an advanced manufacturing process automatically produce complex geometric shapes a computer-aided design model without tools, molds, or fixtures. This automated has been applied diverse industries today because it revolutionize industry with expected benefits. research study on performance pipelines under static loads structure's safety against possible development progressive failure. includes numerical study, where was studied many parameters value pipeline. (a) material (steel, traditional concrete, concrete printed), (b) thickness (20, 30, 40 mm), (c) type (moist sandy soil, saturated moist cohesive soil). Different results were obtained depending all materials' behavior similar case soil. Doi: 10.28991/CEJ-2022-08-01-01 Full Text: PDF
