1. 1. Numerical simulations of pore pressure on concrete buttress dams

   University essay from KTH/Betongbyggnad

   Author : Mohammed Abdi; Dimitirios Ntzimanis; [2022]
   Keywords : Porepressureanalysis; upliftpressure; buttressdams; drainage; groutcur- tain; rockfractures; damsafety; RIDAS.;

   Abstract : Uplift pressure is one of the most dominant forces on a dam structure. Difference in head water and tail water creates a hydraulic gradient resulting an upward oriented pressure called uplift pressure, which reduces the dam safety against sliding. READ MORE

3. 2. Influence of Foundation Modelling on the Seismic Response of a Concrete Dam

   University essay from KTH/Betongbyggnad

   Author : Stella Harrison; Siri Nöjd; [2021]
   Keywords : concrete dam; earthquake; finite element analysis; free-field forces; mass foundation; betong dam; jordbävning; finita element analys; free-field forces; inkluderad bergsmassa;

   Abstract : It is of great importance to ensure the structural safety of dams during earthquakes since a failure may cause catastrophic consequences. Conventional computation of the structural response of dams is based on a simplified approach where the foundation is considered as massless. READ MORE

4. 3. Design of RCC gravity dam and FEM modelling in GeoStudio - Longtan dam

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Patrick Lucas Arkadiusz Bochnak; Maria Eugenia Correa Saracco; [2020]
   Keywords : RCC; China; Longtan dam; Flood routing; GeoStudio; Technology and Engineering;

   Abstract : China’s rapid economic development has led to a continuously increasing energy demand and the country is the world’s biggest energy user as of today. The country accounts for around 23% of the global energy production, but 70% of the Chinese energy is generated with coal power and China is the biggest emitter of CO2 in the world. READ MORE

5. 4. An Exploratory Study of Drones Used for Safety Purposes on Outdoor Construction Sites

   University essay from KTH/Industriell ekonomi och organisation (Inst.)

   Author : Ivar Makadsi; Maikel Makdisi-Somi; [2019]
   Keywords : Construction safety; drone adoption; technology adoption frameworks; construction site safety; construction technology adoption models; Byggsäkerhet; drönar adaptering; teknologiska adapteringsramverk; byggarbetsplatssäkerhet; bygg specifika teknologiska adapteringsramverk;

   Abstract : Syftet med denna studie är att undersöka faktorer som påverkar adoptionen av drönare för säkerhetsskäl på byggarbetsplatser, och att fastställa hur dessa faktorer påverkar adopteringen. Detta bidrar till att teknologiskt modernisera byggbranschen samt fylla en lucka i befintlig litteratur om adoptionen av drönare för säkerhetsskäl. READ MORE

6. 5. 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.
