1. Analysis of rock grouting with variable injection pressure
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Rock grouting is an effective technique frequently used in rock engineering to reduce groundwater ingress and increase the stability of surrounding rock mass. The real time grouting control (RTGC) is one of widely used analytical models to predict the grouting process. LÄS MER
2. Groundwater Inflow into Fractured Rock Tunnels
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Groundwater inflow is a challenge in construction of tunnels in fractured bedrocks since it affects the safety function of tunnels and leads to potential problems in the surrounding environment, such as subsidence, dropdown of the groundwater table. Quantification of groundwater inflow into the tunnel is also important for design of grouting in the construction of the tunnel. LÄS MER
3. Jämförande klimat- och energianalys av tunneldrivningsmetoder
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : En ny tunnelbanelinje på åtta kilometer ska anläggas i Stockholm mellan Älvsjö och Fridhemsplan där WSP har fått i uppdrag att utföra ett lokaliseringsarbete som är ett inledande stadie i projektet. Som en del i lokaliseringsutredningen ingår att välja vilken tunneldrivningsmetod som ska användas för tunneldrivningen där konventionell drivning med borrning och sprängning jämförs med fullortsborrning med en tunnelborrmaskin.

4. Development of grout for deep shaft
M1-uppsats, KTH/Byggteknik och designSammanfattning : In tunnel engineering one of the most important factors are the groundwater flow. To solve this problem a method called grouting is commonly used. In this study grout mixes are developed based on specific requirements for a deep shaft located next to a body of water. LÄS MER
5. State of the Art Report on Cement Based Grout Properties and Dynamic Grouting
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : Dynamic grouting in rock mass has been studied since 1985 while desired penetration in rock masses with fine fractures is still a challenge because of uncertainty and complexity in the grouting process. This has attracted the attention of researchers in different countries and regions, especially in some Nordic countries such as Sweden. LÄS MER
