  1. 1. Analysis of underground concrete pipelines subjected to seismic high-frequency loads

    Författare :Roghayeh Abbasiverki; Anders Ansell; Jan Laue; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Earthquake; High-frequency; Underground; Pipelines; Reinforced concrete; Inclined bedrock; Jordbävning; Högfrekvent; Underjordisk; Rörledningar pipelines ; Armerad betong; Lutande berggrund; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Buried pipelines are tubular structures that are used for transportation of important liquid materials and gas in order to provide safety for human life. During an earthquake, imposed loads from soil deformations on concrete pipelines may cause severe damages, possibly causing disturbance in vital systems, such as cooling of nuclear power facilities.

  3. 2. Groundwater Vulnerability Assessment to pollution in Different Soil and Rock Materials

    Författare :Twana Abdullah; Nadhir Al-Ansari; Sven Knutsson; Jan Laue; Sabbar Alqaisi; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Groundwater; Vulnerability; DRASTIC; VLDA; Modification; Soil Mechanics; Geoteknik;

    Sammanfattning : The augmentation of human population regularly corresponds with change in the land cover, including expansion of urban areas, which imposes increasing the available amount of domestic and drinking water. The study area, Halabja-Saidsadiq Basin, is situated in the Northeast of Iraq and is one of the major groundwater sources of the region. LÄS MER

  4. 3. Soil Modification by adding small amounts of binders : A laboratory study

    Författare :Wathiq Jasim Al-Jabban; Jan Laue; Sven Knutsson; Nadhir Al-Ansari; Paolo Simonini; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Soil stabilization through addition of a hydraulic binder is a method frequently used to modify and improve engineering properties of soft soils. Additives like cement and lime are typically used as stabilizers. More recently, industrial by-products, such as fly ashes, cement kiln dust, blast furnace slags and other slags have been used.

  5. 4. Potential Use of Aquifer Thermal Energy Storage System in Arid Regions

    Författare :Qais Al-Madhlom; Jan Laue; Nadhir Al-Ansari; Sabbar Abdullah Saleh; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aquifer thermal energy storage system; ATES; site selection; seepage velocity; aquifer vulnerability; DRASTIC; arid regions; ArcMap GIS; Soil Mechanics; Geoteknik;

    Sammanfattning : After the Oil Crises in 1973, which meant higher energy costs, the world started to look for other sources of energy. This led to the development of renewable energy techniques. Because of the intermittent nature of renewable energy, storage systems were also developed. LÄS MER

  7. 5. Large-scale testing of granular material

    Författare :Elin Bergliv; Jan Laue; Tommy Edeskär; Stefan Larsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Sammanfattning : The main problem to investigate in this study is if larger grained materials, up to 200 mm nominal size, could be used as an embankment material for high-speed railways. High-speed railways have very strict settlement requirements, allowing only very small settlements to ensure safety. LÄS MER
