  1. 1. Finite Element Modeling of Installation Effects of Soil-Cement Columns

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Anne Holtmeier; [2022]
    Keywords : Deep Mixing; Soil Stabilization; Installation; Finite Element Method; PLAXIS;

    Abstract : Since the 1970's deep mixing columns have been widely used all over the world to improve the performance of soft soil in regard to bearing capacity or deformation behaviour. They are installed by mixing a binding agent, e.g. cement, in situ with the soil. READ MORE

  3. 2. Development of grout for deep shaft

    University essay from KTH/Byggteknik och design

    Author : Karl Lindberg; Adam von Krusenstierna; [2021]
    Keywords : Rock injection; Grout; Shaft; Laboration; Cement; Cement mixture; Bergsinjektering; Injekteringsbruk; Schakt; Laboration; Cement; Cementblandning;

    Abstract : In tunnel engineering one of the most important factors are the groundwater flow. To solve this problem a method called grouting is commonly used. In this study grout mixes are developed based on specific requirements for a deep shaft located next to a body of water. READ MORE

  4. 3. 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

  5. 4. 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
