  1. 1. Comparing Groundwater Drawdown with Estimated Influence Radius – A Case Study of Infrastructural Projects in Sweden

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Staffan Druid; [2022]
    Nyckelord :Influence radius; analytical formula; groundwater lowering; sensitivity; Influensradie; analytisk beräkning; grundvattenavsänkning; känslighet;

    Sammanfattning : Infrastructural projects may sometimes require excavation of soils and the groundwater table to be lowered, temporarily or permanently. As there are risks in connection to groundwater lowering, the extent of the affected area is of interest. LÄS MER

  3. 2. Stochastic Settlement Model Including Creep Effects : Simulation of Groundwater Induced Subsidence

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Pierre Wikby; Ragnar Andersson; [2020]
    Nyckelord :creep settlement; secondary compression; geotechnical uncertainty; EMBANKCO; groundwater drawdown; time-dependent settlement model; krypsättningar; Sekundärkompression; geoteknisk osäkerhet; EMBANKCO; grundvattensänkning; tidsberoende sättningsmodell;

    Sammanfattning : When underground openings are constructed, groundwater inflow can occur, which might lead to ground settlements, namely in clay. In these types of construction projects, it is beneficial to be able to quantify risks related to these settlements. A framework developed by Sundell et al. (2019, Risk Analysis, Vol. LÄS MER

  4. 3. Grundvattenpåverkan kring schakter. - En jämförelse mellan olika analytiska beräkningsmetoder

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Axel Barkestedt; [2019-10-30]
    Nyckelord :;

    Sammanfattning : To be able to predict the effects on groundwater related to drawdown is of great importance to make sure that protected objects, such as drinking water wells and vulnerable ecosystems, are not affected. To predict the size of the area that will be affected by a drawdown, an analytical solution is often used to calculate the radius of influence. LÄS MER

  5. 4. An Insight in the Mälarbanan Project : A Study of the Hydrological and Geotechnical Aspects of the Mälarbanan Project

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Aksel Rahman; [2019]
    Nyckelord :settlement; groundwater; drawdown; soil; clay; CRS; sättningar; grundvatten; sänkning; jord; CRS; lera;

    Sammanfattning : In “Mälarbananprojektet”, Trafikverket (The Swedish Transport Administration in Stockholm) want to expand the railway. Mälarbanan is at the present a railway that extends between Stockholm and Hovsta. LÄS MER

  7. 5. Modeling contingency infiltration scenarios in MODFLOW : Stockholm Bypass and tunnel induced groundwater drawdown

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Aslan Abdo; [2019]
    Nyckelord :tunnel induced groundwater drawdown; MODFLOW; artificial recharge; land subsidence; grundvattenavsänkning; tunnel inläckage; MODFLOW; infiltration; sättning;

    Sammanfattning : Subsurface constructions, such as tunnels, create hydrogeological challenges in mitigating risk of subsidence due to groundwater drawdown. Presenting readily made precautionary mitigation plans, such as strategically planned artificial recharge applications, can help effectivise the mitigation process. LÄS MER
