  1. 31. Modeling contingency infiltration scenarios in MODFLOW : Stockholm Bypass and tunnel induced groundwater drawdown

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

    Abstract : 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. READ MORE

  2. 32. Evaluating undrained shear strength of clay with DPSH-A - A down to earth assessment of the applicability in Scania, Sweden

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

    Author : Julia Knutsson; [2018]
    Keywords : Technology and Engineering;

    Abstract : The undrained shear strength of cohesive soils is an important parameter to assess in geotechnical investigations. It is normally evaluated with the cone penetration test (CPT) but problems with penetrating coarse, heterogeneous materials that is also hard, such as clay till, have pointed the interest towards other possible in-situ methods.

  3. 33. Settlement calculation for lime/cement column improved clay : Analytical and numerical analyses related to a case study

    University essay from KTH/Jord- och bergmekanik

    Author : Hulumtaye Kefyalew Yederulh; [2018]
    Keywords : LCC; deep mixing; consolidation settlement; rate of consolidation; numerical analysis; analytical analysis; field measurement.; KC-pelare; djupstabilisering; konsolideringssättningar; konsolideringsgrad; numerisk analys; analytisk analys; fältmätningar;

    Abstract : The dry deep mixing method is widely used to improve a soft clay soil to increase the shear strength as well as to reduce the time for consolidation. It is a mechanical mixing process that makes parts of the soil stiffer than its original strength. It is mainly applicable to soft clay or peat soil. READ MORE

  4. 34. Slope Stability Evaluation from a RiskManagement Perspective : Case Study: the Slussen project in Stockholm

    University essay from KTH/Jord- och bergmekanik

    Author : Louise Larsson; [2018]
    Keywords : Slope stability; shear strength; uncertainties; risk management; Släntstabilitet; Skjuvhållfasthet; riskhantering; osäkerheter;

    Abstract : Site characterization and the subsequent determination of soil strengthparameters constitute a significant part of slope stability assessment.Geotechnical engineering is always governed by great uncertainties sincethe soil properties are challenging to estimate for a large soil volume.

  5. 35. LABORATORY TESTING RELATED TO UNLOADING MODULUS OF SOFT CLAY

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

    Author : Sofia Hasselberg; [2018]
    Keywords : CRS; unloading modulus; storage time; clay; Technology and Engineering;

    Abstract : The unloading modulus, together with the permeability, are responsible for the swelling process of a soil that is subjected to unloading. Studies to examine the unloading modulus of clay has previously been performed and several relationships describing this parameter has hence been developed. READ MORE
