  1. 6. Optimization of support in rock pillars between two parallel tunnels

    University essay from KTH/Jord- och bergmekanik

    Author : Alexander Kote; Sohaib Ishaq; [2022]
    Keywords : tunnel; rock pillar support; rock pillar stability; rock mass; stresses; arching effect; Nyckelord: tunnel; bergförstärkning; bergpelare; bergmassa; spänningar; valveffekt;

    Abstract : When two parallel tunnels are excavated under high to moderate horizontal in-situ stresses combined with minor deformations in the pillar between the tunnels, the in-situ stresses can be redistributed over the tunnels in form of two compressive arches and are transferred from the roof to the abutments of the two tunnels. At additional deformations in the pillar, a new redistribution of the stresses can occur creating one compressive arch over both of the tunnels. READ MORE

  3. 7. Timber pile-supported road embankment : Numerical and analytical analysis of field monitoring project E4 Råneå

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Kent Nystedt; [2022]
    Keywords : Geosynthetic reinforcement; Geosynthetic reinforced pile supported embankment; Pile distance; Embankment height; Finite element method; Pile efficacy;

    Abstract : The previous E4 Råneå road embankment was prone to flooding. Risk of flooding in combination with settlements of the road due to the weak underlying sulphide soil was problematic. The Swedish Transportation Administration improved the length section E4 Råneå by rebuilding the road using the method light embankment piling. READ MORE

  4. 8. 2D Modelling of Geosynthetically Reinforced Piled Embankments : Calibration Methods in PLAXIS 2D & Review of Analytical Guidelines

    University essay from KTH/Jord- och bergmekanik

    Author : Maya Sleiman; [2021]
    Keywords : ;

    Abstract : 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.

  5. 9. Soil reinforcement with geopolymer : A FEM study in the Old Town subway track adjacent to Söderströmsbron

    University essay from KTH/Byggteknik och design

    Author : Alexandra Mikha; Gina Radouani; [2020]
    Keywords : Plaxis 2D; Finite element analysis; geopolymer; interference-free reinforcement; Old Town; Plaxis 2D; finita element analys; geopolymer; störningsfri förstärkning; Gamla Stan;

    Abstract : Söderströmsbron is the bridge that leads the subway between Slussen and Gamla Stan in Stockholm, the capital of Sweden. It is one of the busiest routes in the entire SL traffic system. READ MORE

  6. 10. VERTICAL ELLIPTICAL ACCESS-SHAFTS Geometrical optimisation through FE-modelling

    University essay from Lunds universitet/Geoteknik; Lunds universitet/Institutionen för byggvetenskaper

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

    Abstract : 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. READ MORE
