1. 1. Three-dimensional effects in slope stability for shallow excavations : Analyses with the finite element program PLAXIS

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

   Author : Niclas Lindberg; [2020]
   Keywords : ;

   Abstract : The purpose with this study was to investigate the impact of three-dimensional effects in slope stability for three-dimensional excavations and slopes with cohesive soils and compare the results with the method provided by the Swedish commission of slope stability in 1995 regarding three-dimensional effects. Both the factor of safety and the shape of the slip surface was compared between the methods but also the results from their equivalent two-dimensional geometry. READ MORE

3. 2. Linear and non-linear FE-analysis of cracking behavior of wing walls in integral bridges

   University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

   Author : Andreas Ekman; Christoffer Sandin; [2018]
   Keywords : Non linear FE-modelling; Concrete Damage Plasticity; Wing wall; Crack propagation; Serviceability Limit State; Slab Frame Bridge; Technology and Engineering;

   Abstract : Wing walls on slab frame integral bridges has traditionally been designed for mainly earth pressure and its self-weight. It has also been designed separately from the rest of the bridge. Traditionally no 3D effects have been considered in the design of the wing walls. READ MORE

4. 3. Comparison of ballasted and ballastless bridges for high speed trains

   University essay from KTH/Bro- och stålbyggnad

   Author : David Matos Sánchez; Maša Nikolic; [2016]
   Keywords : High-speed train; concrete bridge; beam bridge; dynamic; 3D dynamic;

   Abstract : The purpose of the project is to investigate the difference in performance between ballasted and ballastless railway bridges dedicated to high speed trains by taking into account both static and dynamic requirements. The main questions are: a) whether choosing a ballastless bridge results in a more slender section due to the lower self-weight b) if the design of bridges for high speed trains is governed by the static or by the dynamic requirements.

5. 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
