Degradation of permafrost—perennially frozen ground that often contains subsurface ice—makes it dif9icult to build and maintain infrastructure including roads, buildings, pipelines, and airports. As ground ice melts, soils shift and collapse making the ground unstable thus jeopardizing infrastructure at the surface.

Foundation (engineering)

Author: William E. Schnabel, Douglas J. Goering, and Aaron D. The Arctic is often considered ground zero for climate change because arctic air temperatures are rising at approximately twice the rate compared to the rest of the globe Meredith et al. However, the diverse facets of arctic climate change e. Impacts include erosion of arctic shorelines Jones et al. But a key element unique to cold regions is the impact of a warming climate on permafrost.

Permafrost Engineering on Impermanent Frost

Arslan, Haydar. Design of pipelines across permafrost terrain differs from that of pipelines where there is no permafrost. A buried pipeline is subject to a variety of internal and external loads such as frost heave and thaw load induced by relative movements between the pipeline and the surrounding soils. Frost heave occurs as fine-grained soil i. Thaw settlement occurs when soil with excess ice i. Both differential heave and differential settlement can lead to large pipeline strain.

How is permafrost degradation affecting infrastructure?

In engineering, a foundation is the element of a structure which connects it to the ground, and transfers loads from the structure to the ground. Foundations are generally considered either shallow or deep. The design and the construction of a well-performing foundation must possess some basic requirements:. Buildings and structures have a long history of being built with wood in contact with the ground.

Pipelines in permafrost: geotechnical issues and lessons

 - Танкадо требует, чтобы мы признали существование ТРАНСТЕКСТА. Но он несколько опоздал. Сьюзан хотела что-то сказать, но ее опередил Джабба: - Значит, Танкадо придумал шифр-убийцу.  - Он перевел взгляд на экран. Все повернулись вслед за .

Пальцы Беккера схватили воздух, а дверь повернулась. Девушка с сумкой была уже на улице. - Меган! - завопил он, грохнувшись на пол.

 Ты хочешь сказать, что это уродливое дерьмовое колечко принадлежит. Глаза Беккера расширились. - Ты его. Двухцветный равнодушно кивнул. - Где оно? - не отставал Беккер.

Она знала, что, если они не будут терять времени, им удастся спасти эту великую дешифровальную машину параллельной обработки. Каждый компьютер в мире, от обычных ПК, продающихся в магазинах торговой сети Радиошэк, и до систем спутникового управления и контроля НАСА, имеет встроенное страховочное приспособление как раз на случай таких ситуаций, называемое отключение из розетки.
