  1. 1. Timber pile-supported road embankment : Numerical and analytical analysis of field monitoring project E4 Råneå

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Kent Nystedt; [2022]
    Keywords : Geosynthetic reinforcement; Geosynthetic reinforced pile supported embankment; Pile distance; Embankment height; Finite element method; Pile efficacy;

    Abstract : The previous E4 Råneå road embankment was prone to flooding. Risk of flooding in combination with settlements of the road due to the weak underlying sulphide soil was problematic. The Swedish Transportation Administration improved the length section E4 Råneå by rebuilding the road using the method light embankment piling. READ MORE

  3. 2. Evaluation of long-term performance of sodium silicate grouted in embankment dams

    University essay from KTH/Jord- och bergmekanik

    Author : Jenny Fu; [2019]
    Keywords : Sodium silicate; water glass; embankment dams; remedial grouting; dam monitoring;

    Abstract : Embankment dams is the most common type of dams in operation inSweden today. Due to the nature of embankment dams, seepage throughthem will always occur. If the seepage velocity exceeds a critical velocity,internal erosion is initiated, which could lead to damage in form of pipingand sinkholes. READ MORE

  4. 3. 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.

  5. 4. Groundwater Chemistry in the Amazon Rainforest

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Jennifer Leone; [2017]
    Keywords : Amazon; carbon flux; chemical analysis; groundwater; nutrients;

    Abstract : Groundwater chemistry is highly variable and dependent on environmental conditions, and it is not entirely understood how all these factors contribute to groundwater chemistry. This study aims to examine some of the factors that contribute to groundwater heterogeneity in the Amazon Rainforest. READ MORE

  6. 5. Spatial variation in uplift pressure and correlation with rock mass conditions under two buttress dams : A case study of Ramsele and Storfinnforsen dams

    University essay from KTH/Jord- och bergmekanik

    Author : Diego Alcalá Perales; [2016]
    Keywords : Concrete dams; buttress dam; uplift pressure; probabilistic distribution; joint aperture; RQD.;

    Abstract : Uplift water pressure is one of the dominating forces with signicant impact acting on a dam. It is usually measured with piezometers installed along the dam. However, the value of the pressure along the dam is often hard to measure due to the limited number of piezometers available (Bernstone et al., 2009). READ MORE
