  1. 1. VERTICAL ELLIPTICAL ACCESS-SHAFTS Geometrical optimisation through FE-modelling

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Geoteknik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Björn Elfving; Aron Sandström; [2020]
    Nyckelord :Access-shafts; FE-modelling; Plaxis; Robot; Elliptical; Circular; Optimisation; Geotechnical; Engineering; Retaining; Structures; Tunnel; Soil; Interaction; Technology and Engineering;

    Sammanfattning : Urbanisation is causing densification of cities and more and more facilities are being placed in the underground to utilise the urban space as efficiently as possible. Access to the underground is obtained by constructing vertical access shafts. LÄS MER

  3. 2. Data interpolation for groundwater modelling : How choice of interpolation method and sample size affect the modelling results

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Frida Agerberg; [2020]
    Nyckelord :Geohydrology; Groundwater; Modelling; Interpolation; SEEP W; Surfer; Geohydrologi; Grundvatten; Modellering; Interpolering; SEEP W; Surfer;

    Sammanfattning : Over the past several decades, the use of groundwater modelling has been increasing in order to better evaluate the complexities inherent in hydrogeological calculations. Information required for groundwater modelling is for example elevation of soil and bedrock layers, which often is collected by drilling. LÄS MER

  4. 3. Tvådimensionell grundvattenmodellering av påverkansområdet inför tunnelkonstruktion i Glömstadalen

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

    Författare :Emelie Johansson; [2018]
    Nyckelord :Groundwater modelling; two-dimensional modelling; tunnels in rock; influence area; SEEP W; Grundvattenmodellering; tvådimensionell modellering; bergtunnlar; påverkansområde; SEEP W;

    Sammanfattning : When building tunnels in rock, an inflow of groundwater is likely induced. Depending on the hydraulic properties of the rock and the surrounding soils, the inflow may cause a decline in the groundwater level above the tunnel line with possible consequences for nearby well facilities or groundwater dependent environments.

  5. 4. Internal Erosion and Dam Stability : Analysis of the internal erosion effects on stability of an embankment dam

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

    Författare :Arthur Jedenius; [2018]
    Nyckelord :Internal erosion stability finite element analysis method plaxis slope seep;

    Sammanfattning : Embankment dams encounter several problems in terms of dam safety. One of those problems is called internal erosion. This phenomenon is induced by the movement of fine particles within the dam due to seepage forces. If the dam is not able to self-heal, the eroded zones will increase which will eventually cause the dam to fail. LÄS MER

  7. 5. Grundvattensänkning vid schakter och byggnadsverk - En jämförelse av olika beräkningsmetoder

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Philip Håkansson; [2017]
    Nyckelord :Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : Many construction projects, entail excavations into water-bearing soils. As a consequence of this a groundwater lowering must be made which can cause major environmental impacts, such as drainage of adjacent rivers or wetlands or subsidence of adjacent buildings. LÄS MER
