1. 1. Probabilistic settlement analysis for embankments using preloading without surcharge

   University essay from KTH/Jord- och bergmekanik

   Author : Karl Escher; [2022]
   Keywords : Bayesian statistics; uncertainty; geotechnical risk evaluation; preloading; consolidation; embankments; ground improvement; dependence modelling.;

   Abstract : Preloading without a surcharge is a common method for ground improvement. Thereare however uncertainties related to the number of site investigations and the partialfactor method has been identified as a problem. READ MORE

3. 2. Study of Improved Sampling and Preparation of East-Swedish Glacial Clay

   University essay from KTH/Jord- och bergmekanik

   Author : CLARA GARCIA DE HERREROS; [2020]
   Keywords : clay; disturbance; sample quality; block sampling; preconsolidation pressure; shear strength.;

   Abstract : The aim of this study is to determine if the mini block sampling technique couldoffer a complement to the Swedish standard StII piston sampler for achieving higherquality samples. The principle is that having a greater diameter the sample is meticulouslytrimmed to the usual geometry, so that the periphery of the sample is not disturbedby the sampling procedure and the same testing equipment can be employed.

4. 3. Modelling of a compensated foundation in GeoSuite Settlement

   University essay from KTH/Jord- och bergmekanik

   Author : Linnea Hermansson; Rebecka Söderberg; [2020]
   Keywords : Compensated foundations; Load compensation; Lightweight material; Clay; Settlements; Creep; GeoSuite Settlement; Kompensationsgrundläggning; Lastkompensation; Lättfyllning; Lera; Sättningar; Krypning; GeoSuite Sättning;

   Abstract : The world today is constantly growing, creating a need of new roads and residential areas. New constructions lead to an increased load onto the soil, which can result in deformations when the soil layers underneath are compressed. To reduce the increased load on the soil, a compensated foundation can be used. READ MORE

5. 4. Relationship between Shear-Wave Velocity and Consolidation Parameters of Peat

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

   Author : Oskar Markström; [2018]
   Keywords : shear wave velocity; peat; constant rate of strain; consolidation parameters; von Post; Technology and Engineering;

   Abstract : There is a need of developing methods for evaluating material parameters for peat. It is hard and costly to obtain undisturbed samples for laboratory testing of the peat. Therefore, in this thesis the possibility of using in situ measurements of the shear wave velocity for first order estimates of the consolidation parameters has been investigated. READ MORE

6. 5. Empirical correlation between undrained shear strength and preconsolidation pressure in Swedish soft clays

   University essay from KTH/Jord- och bergmekanik

   Author : Erik Persson; [2017]
   Keywords : undrained shear strength; preconsolidation pressure; empirical correlations; fall cone test; direct simple shear test; correction factor; soft clay; odränerad skjuvhållfasthet; förkonsolideringstryck; empiriska korrelationer; fallkonförsök; direkta skjuvförsök; korrektionsfaktor; lera;

   Abstract : The undrained shear strength and preconsolidation pressure are key parameters in describing the characteristics of soft clays. The two parameters both reflect the clay’s structure and state of stress, and hence empirical correlations for undrained shear strength normalized with respect to preconsolidation pressure are widely used to assess soil behavior.
