1. 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
2. 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
3. Triaxial testing of lime/cement stabilized clay : A comparison with unconfined compression tests
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : Detta examensarbete presenterar resultat från en laboratoriestudie på en lera från Enköping stabiliserad med kalk och cement. I laboratoriet har isotropiskt konsoliderade odränerade aktiva triaxialförsök utförts på provkroppar och jämförts med enaxliga tryckförsök som utförts på provkroppar från samma inblandningstillfälle.

4. Shear Resistance Degradation of Lime –Cement Stabilized Soil During Cyclic Loading
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : This thesis presents the results of a series of undrained cyclic triaxial tests carried out on four lime-cement stabilized specimens and clay specimen. The shear resistance degradation rate of lime-cement column subjected to cyclic loading simulated from heavy truck was investigated based on stress-controlled test. LÄS MER
5. Korrelation mellan hållfasthet i kalkcementpelare och oförstärkt lera : En studie av sonderingar utförda på projekt BanaVäg i Väst
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : A today common soil reinforcement method is the installation of lime-cement columns. Lime-cement columns have been used since the 1970’s and have been a useful method for stabilizing soil at great depths. It is mostly used for stabilizing road and railway embankments because the method is economically viable and the columns are easy to install. LÄS MER
