  1. 1. Numerical modelling of lime-cementcolumns in the passive zone of excavations in soft clays

    University essay from KTH/Jord- och bergmekanik

    Author : Anaëlle Gilot; [2021]
    Keywords : Deep mixing; lime-cement columns; excavations; clay; finite element method; advanced constitutive model; Mélange profond; colonnes de chaux-ciment; excavations; argile; méthode des éléments finis; modèle constitutif avancé; Jordförstärkning med kalk-cement pelare; utgrävningar; lera; finita elementmetoden; avancerad konstitutiv modell;

    Abstract : Excavations in soft clays come with a number of specific challenges. The use of lime-cement columns in the passive zone of such works represents a promising solution to some of these problems, such as basal heave stability or excessive deformations. READ MORE

  3. 2. 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. 3. The choice of soil improvement at railroad constructions

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Author : Emil Johansson; Viktor Johansson; [2017]
    Keywords : bankpålning; jordförstärkning; jordförstärkningsmetod; kalkcementpelare;

    Abstract : Vid byggnation av järnväg måste man som projektör ta hänsyn till om marken behöver förstärkas eller ej. Detta gör att man står inför viktiga avväganden vid valet av jordförstärkningsmetod. READ MORE

  5. 4. Short-term deformations in clay under a formwork during the construction of a bridge : A design study

    University essay from KTH/Jord- och bergmekanik

    Author : Alexander Berglin; [2017]
    Keywords : Plaxis; Short-term deformations; Elasticity modulus; Correlations; Small-strain stiffness; Korttidssättningar; Elasticitetsmodulen; Korrelationer;

    Abstract : During the casting of a concrete bridge deck, the temporary formwork is causing the underlying ground to deform if a shallow foundation solution is used. There are often demands on the maximum deformation of the superstructure when designing the foundation for the formwork. READ MORE
