1. Finite Element Modeling of Installation Effects of Soil-Cement Columns
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : 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. LÄS MER
2. Development of grout for deep shaft
M1-uppsats, KTH/Byggteknik och designSammanfattning : 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. LÄS MER
3. Numerical modelling of lime-cementcolumns in the passive zone of excavations in soft clays
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : 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. LÄS MER
4. Numerisk beräkning av krypsättningar i pelarförstärkt lera
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : I detta examensarbete har en utredning gjorts med syftet att undersöka lämpligheten att genomföra en djupstabilisering med multicementpelare (MC-pelare) i ett område med högt ställda sättningskrav. Detta genom att numeriskt simulera hur djupstabiliserad lera kan bete sig vid belastning med avseende på långtidsdeformationer. LÄS MER
5. Settlement calculation for lime/cement column improved clay : Analytical and numerical analyses related to a case study
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : 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. LÄS MER
