1. Jet Grout Bottom Plug in Deep Excavations : Numerical Analysis of a Tunnel Project
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : This master thesis has investigated the performance of a deep excavation with a jet grout bottom plug used to prevent bottom heave and hydraulic uplift failure. The concept of a jet grout plug as a structural and sealing component in a specific case was studied, namely one of the tunnel sections of The West Link tunnel project in Gothenburg. LÄS MER
2. Numerical simulations of pore pressure on concrete buttress dams
Master-uppsats, KTH/BetongbyggnadSammanfattning : 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. LÄS MER
3. Metodik för trådlös dataöverföring från damminstrumentering till en mätdatabastitel
Master-uppsats, Uppsala universitet/ElektricitetsläraSammanfattning : Hydropower dams have been helping our society with electricity production for a long time now. In the past there have been several serious dam accidents in many parts of the world and the continuous work with dam safety is very important to Swedish hydropower industry. LÄS MER
4. Day Zero: Communicating the water crisis in Cape Town, 2015-2018 : A qualitative study about the communication during the water crisis and how the public responded to the messages
Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)Sammanfattning : Stigande urbanisering och större befolkningar har ökat trycket på städer och deras förmågor att förse alla med de vardagstjänster som städerna vanligtvis har kapacitet att erbjuda. Att förse alla med dricksvatten är något som har blivit en utmaning då vattenanvändningen har stigit samtidigt som vattentillgången varierar beroende på nederbörd, och potentiellt minskat på grund av klimatförändringarna.

5. An alarm system for pore pressure measurements in the foundation ofconcrete dams : a case study of Storfinnforsen buttress dam
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : 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.
