  1. 1. Back analysis of rock mass properties in the regional fault zone under Lake Mälaren

    University essay from KTH/Jord- och bergmekanik

    Author : Jiaqi Liu; [2022]
    Keywords : Rock mass property; back analysis; tunnel deformation; optimization algorithm; numerical analysis; Bergmassans egenskaper; bakåtanalys; tunnleldeformation; optimeringingsalgoritm; numeriska analyser.;

    Abstract : The properties of the surrounding rock mass in underground projects have significant impacts on the design and construction. However, it is quite challenging to evaluate rock mass properties due to the great uncertainties of the geological conditions. READ MORE

  2. 2. Numerical simulations on passenger vehicles equipped with a cover under transportation

    University essay from

    Author : Jaime Mateo Barroso; [2019-07-03T14:32:12Z 2019-07-03T14:32:12Z 2017]
    Keywords : Transport; Grundläggande vetenskaper; Hållbar utveckling; Strömningsmekanik och akustik; Transport; Basic Sciences; Sustainable Development; Fluid Mechanics and Acoustics;

    Abstract : The concern of the car companies to offer an image of quality to their clients has led to take care of every single detail. An example of this, is that newly produced cars are now being covered during their transportation on trucks. The design of the covers involve several wind tunnel tests for each new car model.

  3. 3. Optimization of Extreme Environment Cyclic Testing : Analysis of thermal cycle load cases on a plastic cab component through simulation and testing

    University essay from KTH/Fordonsdynamik

    Author : John Sedin; [2016]
    Keywords : ;

    Abstract : The purpose of this Master thesis was to deepen the knowledge and understanding regarding control parameters for the Extreme Environment Cyclic Testing (EECT) on interior and exterior cab components. The investigated parameters were temperature gradient, length of the warm and cold sections and number of cycles. READ MORE

  4. 4. Numerical Modelling and Sensitivity Analysis of Tunnel Deformations in London Clay

    University essay from KTH/Jord- och bergmekanik

    Author : Malin Sandström; [2016]
    Keywords : Small-strain stiffness; Mohr-Coulomb; Plaxis; sensitivity analysis; tunnels; London Clay;

    Abstract : In dense cities, the interactions between all structures, from tall skyscrapers to complex underground tunnel systems, need to be carefully analysed as soon as a new project is considered. This is necessary because of the stress changes in the soil induced by each new construction. READ MORE

  5. 5. Evaluation of high pressures in grouting using RTGC - a case study

    University essay from KTH/Jord- och bergmekanik

    Author : Simon Nikolaev; [2015]
    Keywords : grouting; grouting pressures; tunnelling project; RTGC-theory; injektering; injekteringstryck; tunnelprojekt; RTGC-teorin;

    Abstract : “Real time grouting control method” är ett koncept för att övervaka och bedöma spridningen av injekteringsbruk under injektering. Målet är att kunna använda penetrationsavstånd som stopkriterium och att kunna övervaka hur injekteringsarbetet fortskrider i realtid, vilket skulle göra injekteringsarbetet mer tids- och kostnadseffektivt.
