  1. 1. 2D Modelling of Geosynthetically Reinforced Piled Embankments : Calibration Methods in PLAXIS 2D & Review of Analytical Guidelines

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Maya Sleiman; [2021]
    Nyckelord :;

    Sammanfattning : This thesis focuses on the 2D modelling of Geosyntheticaly Reinforced Piled Embankments (GRPE) in PLAXIS 2D. In doing so, it explores two main aspects: 1) the calibration of Interface Stiffness Factors (ISFs) governing the soil-pile interaction of Embedded BeamRow (EBR) elements in PLAXIS 2D, and 2) the prospects and limitations of modelling geogrids (GR) in PLAXIS 2D when underlain by EBR elements; although several studies have validates the EBR element in modelling piles, none address the geogrid-EBR interaction and its implications on modelling GRPE systems.

  2. 2. Geogrids in cold climate : Temperature controlled tensile tests & Half-scale installation tests at different temperatures 

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

    Författare :Björn Bonthron; Christian Jonsson; [2017]
    Nyckelord :geogrid; cold climate; low temperature; tensile test; half-scale test;

    Sammanfattning : Due to the findings of extensive damage on geogrids used in a road embankment in northern Sweden, the Swedish Transport Administration (TRV) started to investigate the reason of these damages. Since the geogrids were installed at low temperature, below 0°C, it was suspected that the damages were connected the low temperature. LÄS MER

  3. 3. Upprustningsmetoder för en bankropp : En jämförelse ur ett LCC-perspektiv

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Byggteknik

    Författare :Rehn Karin; [2014]
    Nyckelord :;

    Sammanfattning : In recent years, the Swedish railway track system has been neglected in terms of capacity and maintenance. To adapt the existing system to current traffic load there is a great need for extensive improvement and maintenance. Shortcomings are especially occurring on older embankments running over soft subgrades. LÄS MER

  4. 4. Geosynteter för hållbara vägar : Modell för jämförelse av vägöverbyggnader med eller utan geotextiler och/eller geonät

    Master-uppsats, Akademin för hållbar samhälls- och teknikutveckling

    Författare :Katja Fedorova; [2011]
    Nyckelord :geotextile; geosynthetic; geonet; geogrid; bearing capacity; road deformation; geotextilier; geotextiler; geosynteter; geonät; fiberdukar; armering med geonät;

    Sammanfattning : The different material layers as part of a road construction fill all a function so theroad becomes durable, safe, comfortable and aesthetically pleasing. Recently, anew group of construction materials started to play an important role in roadconstruction – geosynthetics. LÄS MER
