  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. Optimization of structures byincluding modeling of pilefoundations : A parametric study on using stiff supports orpiles in a model

    University essay from KTH/Bro- och stålbyggnad

    Author : Alexander Koba; [2022]
    Keywords : ;

    Abstract : Structural engineers use rules and regulations in the form of Eurocodes and other supplementary guidelines to design different type of structures. However, the uncertainty surrounding each case and the actual outcome that depends on decisions made throughout the design phase are of most importance and must be handled properly from start.

  4. 3. Stochastic Settlement Model Including Creep Effects : Simulation of Groundwater Induced Subsidence

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Pierre Wikby; Ragnar Andersson; [2020]
    Keywords : creep settlement; secondary compression; geotechnical uncertainty; EMBANKCO; groundwater drawdown; time-dependent settlement model; krypsättningar; Sekundärkompression; geoteknisk osäkerhet; EMBANKCO; grundvattensänkning; tidsberoende sättningsmodell;

    Abstract : When underground openings are constructed, groundwater inflow can occur, which might lead to ground settlements, namely in clay. In these types of construction projects, it is beneficial to be able to quantify risks related to these settlements. A framework developed by Sundell et al. (2019, Risk Analysis, Vol. READ MORE

  5. 4. Artificial intelligence to model bedrock depth uncertainty

    University essay from KTH/Jord- och bergmekanik

    Author : Beatriz Machado; [2019]
    Keywords : Machine learning; Artificial intelligence; Kriging; prediction; algorithm.;

    Abstract : The estimation of bedrock level for soil and rock engineering is a challenge associated to many uncertainties. Nowadays, this estimation is performed by geotechnical or geophysics investigations. These methods are expensive techniques, that normally are not fully used because of limited budget. READ MORE

  6. 5. Decision-making model for track system of high-speed rail lines : Ballasted track, ballastless track or both?

    University essay from KTH/Byggvetenskap

    Author : Veronika Sárik; [2018]
    Keywords : ;

    Abstract : During the 50 years of existence of high speed railways, the track structure solutions have developed both in number and in type. As of today, in case of conventional railway, there are 2 main types one could mention: ballasted and ballastless track solutions. READ MORE
