  1. 1. Soil Improvement method by Mass Stabilization : Settlement analysis in stabilized sulfide soil

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

    Author : Albin Åkerlund; [2023]
    Keywords : Mass stabilization; Sulfide soil; settlement.;

    Abstract : Mass stabilization is not a common soil improvement method in Sweden, and even less so in sulfide soils. Previous research indicates that a linear elastic material model is suitable for settlements in stabilized sulfide soil. A construction project in the northern part of Sweden applied mass stabilization in sulfide soil. READ MORE

  3. 2. Effect of increased vertical stress on the state of grains in tailings

    University essay from Luleå tekniska universitet/Geoteknologi

    Keywords : Tailings; Tailings dams; Breakage; Oedometer; Image acquisition analysis; Avfall; Avfallsdammar; Brytning; Ödometer; Bildinsamling och analys;

    Abstract : Tailings storage facilities (TSFs) serve as structures for storing tailings, i.e., waste materials generated by the mining industry. READ MORE

  4. 3. Timber pile-supported road embankment : Numerical and analytical analysis of field monitoring project E4 Råneå

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Kent Nystedt; [2022]
    Keywords : Geosynthetic reinforcement; Geosynthetic reinforced pile supported embankment; Pile distance; Embankment height; Finite element method; Pile efficacy;

    Abstract : The previous E4 Råneå road embankment was prone to flooding. Risk of flooding in combination with settlements of the road due to the weak underlying sulphide soil was problematic. The Swedish Transportation Administration improved the length section E4 Råneå by rebuilding the road using the method light embankment piling. READ MORE

  5. 4. Design of tunnel support for single zones with swelling clay

    University essay from KTH/Jord- och bergmekanik

    Author : Taha Faris Nihayat; [2022]
    Keywords : Swelling clay; Rock support; Weakness zone; Design; Tunnel;

    Abstract : Swelling clay is an important and challenging geological feature in tunnelling projects.The behaviour of swelling clay is influenced by many internal and external factors.This, combined with a lack of experience and knowledge has resulted in challengeswhen accounting for the swelling phenomena.

  6. 5. 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.
