1. 1. VERTICAL ELLIPTICAL ACCESS-SHAFTS Geometrical optimisation through FE-modelling

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

   Author : Björn Elfving; Aron Sandström; [2020]
   Keywords : Access-shafts; FE-modelling; Plaxis; Robot; Elliptical; Circular; Optimisation; Geotechnical; Engineering; Retaining; Structures; Tunnel; Soil; Interaction; Technology and Engineering;

   Abstract : Urbanisation is causing densification of cities and more and more facilities are being placed in the underground to utilise the urban space as efficiently as possible. Access to the underground is obtained by constructing vertical access shafts. READ MORE

3. 2. Data interpolation for groundwater modelling : How choice of interpolation method and sample size affect the modelling results

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

   Author : Frida Agerberg; [2020]
   Keywords : Geohydrology; Groundwater; Modelling; Interpolation; SEEP W; Surfer; Geohydrologi; Grundvatten; Modellering; Interpolering; SEEP W; Surfer;

   Abstract : Over the past several decades, the use of groundwater modelling has been increasing in order to better evaluate the complexities inherent in hydrogeological calculations. Information required for groundwater modelling is for example elevation of soil and bedrock layers, which often is collected by drilling. READ MORE

4. 3. Internal Erosion and Dam Stability : Analysis of the internal erosion effects on stability of an embankment dam

   University essay from Luleå tekniska universitet/Geoteknologi

   Author : Arthur Jedenius; [2018]
   Keywords : Internal erosion stability finite element analysis method plaxis slope seep;

   Abstract : Embankment dams encounter several problems in terms of dam safety. One of those problems is called internal erosion. This phenomenon is induced by the movement of fine particles within the dam due to seepage forces. If the dam is not able to self-heal, the eroded zones will increase which will eventually cause the dam to fail. READ MORE

5. 4. Closure of Lilla Bredsjön Tailings Dam : an Evaluation of the Long-Term Dam Safety Measures

   University essay from KTH/Vattendragsteknik

   Author : Jenny Bramsäter; [2017]
   Keywords : tailings dams; seepage; pore pressure; slope stability; slip surfaces; long-term stability;

   Abstract : The mining industry contributes to enormous amounts of waste all over the world, which places high demands on tailings dams. In Sweden, there are strict regulations regarding the management and treatment of tailings dams, but some dams that were built before these regulations existed still pose a threat to the environment.

6. 5. Safety Evaluation of the Zhaoli Tailings Dam : A seepage, deformation and stability analysis with GeoStudio

   University essay from

   Author : Malin Ljungblad; Johan Bäckström; [2016]
   Keywords : ;

   Abstract :  The mining industry produce large amount of mine waste, also called tailings, which must be kept in tailings dams. In this thesis the safety and stability of a tailings dam have been studied, where some of the tailing material is being used as filling material. The dam has been modelled and simulated using the software Geostudio. READ MORE
