  1. 1. An alarm system for pore pressure measurements in the foundation ofconcrete dams : a case study of Storfinnforsen buttress dam

    University essay from KTH/Jord- och bergmekanik

    Author : Daniel Falcão de Queiroz; [2018]
    Keywords : Buttress dams; dam foundation; pore pressure; alarm system; alarm limits; sliding in the rock mass; uplift pressure; piezometers.; Lamelldammar; dammgrundläggning; portryck; alarm system; alarmgränser; glidning i bergmassan; upptryck; portrycksmätare;

    Abstract : Concrete buttress dams are relatively light structures and less demandingon foundations; because of that, they may have problems with upliftforces and horizontal joints in the area of the dam´s foundation maypresent a failure mode through sliding. The Storfinnforsen dam, thelargest concrete dam in Sweden, had its foundation studied recently andthe discovery of sub-horizontal joints in the bedrock led to the necessityof having the safety of the dam foundation to sliding assessed.

  2. 2. Modeling of pore pressure in a railway embankment

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

    Author : Marcus Vestman; [2018]
    Keywords : PLAXIS; Pore pressure; Railway;

    Abstract : LKAB and Trafikverket want to increase the maximum allowed axial load from 30 tons to 32,5 tons for the northern part of Malmbanan. There are ongoing investigations of the condition of the railway with the current axial load of 30 tons. The investigations do not include one of Trafikverket's concerns about the condition of the railway. READ MORE

  3. 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

  4. 4. Pore water pressure and settlements generated from water driven DTH-drilling : - A field study

    University essay from KTH/Jord- och bergmekanik

    Author : Moa Asplind; [2017]
    Keywords : DTH drilling; hydraulic drilling; settlements; pore pressure; Venturi effect; Sänkhammarborrning; vattendriven borrning; sättningar; porvattentryck; Venturi effekten.;

    Abstract : Foundation work can cause damage to adjacent buildings and infrastructure. Drilling is performed in sensitive areas in urban projects and where the ground conditions are difficult. It is important to be aware of the installation effects from drilling. READ MORE

  5. 5. Consolidation of Soft Sediments Using Artificial Ground Freezing

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Karina Tommik; [2017]
    Keywords : ;

    Abstract : Freeze-thaw cycling is investigated as a possible method for consolidation of fine grained soils. The method relies mainly on phenomena of thaw consolidation. While the soil is subjected to multiple freeze-thaw cycles the water is pressed out of the material as the excess pore pressure dissipates. READ MORE
