  1. 1. Back analysis of rock mass properties in the regional fault zone under Lake Mälaren

    University essay from KTH/Jord- och bergmekanik

    Author : Jiaqi Liu; [2022]
    Keywords : Rock mass property; back analysis; tunnel deformation; optimization algorithm; numerical analysis; Bergmassans egenskaper; bakåtanalys; tunnleldeformation; optimeringingsalgoritm; numeriska analyser.;

    Abstract : The properties of the surrounding rock mass in underground projects have significant impacts on the design and construction. However, it is quite challenging to evaluate rock mass properties due to the great uncertainties of the geological conditions. READ MORE

  3. 2. Tunnel Seismic Prediction in Stockholm Bypass

    University essay from KTH/Jord- och bergmekanik

    Author : Matilda Wessén; Janita Österberg; [2021]
    Keywords : Tunnel Seismic Prediction; TSP; Seismic waves; Stockholm Bypass; Geological mapping; Measurement While Drilling; Tunnel Seismic Prediction; TSP; Seismiska vågor; Förbifart Stockholm; Bergkartering; Measurement While Drilling;

    Abstract : Tunnel Seismic Prediction (TSP) is a geophysical investigation method used to predict the rock conditions ahead of the tunnel face. The method has been used in different types of rock and rock conditions. READ MORE

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

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

    Abstract : 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. READ MORE

  5. 4. The Impact of Fracture Orientation on the Choice of Grout Fan Geometry - a Statistical Analysis

    University essay from KTH/Jord- och bergmekanik

    Author : Fredrik Osterman; [2019]
    Keywords : Rock Fissure Grouting; Grout Fan Geometry; Geology; Discrete Fracture Network; Sprickinjektering i berg; skärmgeometri; geologi; diskreta spricknätverk;

    Abstract : Water ingress into rock tunnels is a problematic phenomenon – especially in urban areas – as a lowered groundwater table may cause harmful settlements. Furthermore, too much ingress can be an incentive for the environmental court to halt the tunnel process, in order to protect the nature as part of a national interest. READ MORE

  6. 5. Exploring the use of GIS-based Least-cost Corridors for Designing Alternative Highway Alignments

    University essay from KTH/Geoinformatik

    Author : Joacim Gärds; Martin Oscarsson; [2019]
    Keywords : GIS; GIT; geoinformatics; alignment; road; Jönköping; Sweden; road planning; geoinformatik; Jönköping; förbifart; transport;

    Abstract : Finding an optimal route for a new highway alignment is a task which requires a lot of resources. In the planning phase, choosing the location of a new highway alignment is very important as it will heavily affect the total construction cost. However, the perfect location of a new highway alignment is ambiguous depending on many parameters. READ MORE
