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. Behavior prediction of concrete dams

   University essay from KTH/Betongbyggnad

   Author : Isak Nilsson; Leonard Sandström; [2020]
   Keywords : Concrete dams; dam monitoring; dam safety; measurement evaluation; databased models i;

   Abstract : As many dams were built around 1950, the expected life span of these dams are about tobe reached. With this, the need for monitoring and increased understanding of the damsstructural integrity increases. In order to prevent failures, two warning signals are defined;alert and alarm. 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. Prediction of early age and time dependent deformations in a massive concrete structure

   University essay from KTH/Betongbyggnad

   Author : Ali Aghili; Haris Ribac; [2018]
   Keywords : Early age concrete; hydration of cement; Storfinnforsen; ConTeSt; crack risk; temperature development; strain; mass concrete structures; measurement plan; Ung betong; hydratation av cement; Storfinnforsens kraftverk; ConTeSt; sprickrisk; temperatur; töjning; massiva konstruktioner; mätningsplanering;

   Abstract : The heat development that occurs due to the hydration of cement is important to consider during casting of massive concrete structures. By using computer programs that are based on finite element methods (FEM), simulations can be performed on the heat- and strength development. 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
