1. Processing of ERT data from Stabilised Columns
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)Sammanfattning : Modern construction sites are associated with high demands on suitable soil conditions, resulting in geotechnical challenges that can be solved using soil stabilisation techniques. The reliability of these techniques is tested using different quality assurance methods. LÄS MER
2. 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
3. Jet grouting as a method for sealing sheet pile excavations in Swedish conditions : A probabilistic approach
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : Jet grouting is a groundimprovement method that creates cemented columns in the soil. The soil isinjected with different pressurized fluids, through the monitor, to replace andcement the soil, often with water cement grout. There are three different commonsystems for ejecting the fluids, the single, double and triple fluid system. LÄS MER
4. Evaluation of long-term performance of sodium silicate grouted in embankment dams
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : 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. LÄS MER
5. Bultförstärkning av berg vid konventionell tunneldrivning : En jämförelse av kamstålsbult och PC-bult
M1-uppsats, KTH/Byggteknik och designSammanfattning : Vid tunneldrivning inom infrastrukturprojekt i Sverige är den mest förekommande bergbulten för permanenta förstärkningar den konventionella kamstålsbulten. En ingjuten bult utan förspänning. Montaget sker genom att med handkraft pressa in bulten i ett cementfyllt borrhål. LÄS MER
