  1. 1. Analysis of rock grouting with variable injection pressure

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Zhuohang Lian; [2022]
    Keywords : Rock engineering; Rock grouting; Variable injection pressure; Dynamic grouting technique;

    Abstract : 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. READ MORE

  3. 2. Groundwater Inflow into Fractured Rock Tunnels

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Mariam Beydoun; [2022]
    Keywords : groundwater inflow; rock tunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynold’s equation; cubic law; grundvatteninflöde; bergtunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynolds equation; cubic law;

    Abstract : 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. READ MORE

  4. 3. Development of grout for deep shaft

    University essay from KTH/Byggteknik och design

    Author : Karl Lindberg; Adam von Krusenstierna; [2021]
    Keywords : Rock injection; Grout; Shaft; Laboration; Cement; Cement mixture; Bergsinjektering; Injekteringsbruk; Schakt; Laboration; Cement; Cementblandning;

    Abstract : 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. READ MORE

  5. 4. State of the Art Report on Cement Based Grout Properties and Dynamic Grouting

    University essay from KTH/Jord- och bergmekanik

    Author : Bowen Meng; [2021]
    Keywords : Dynamic grouting; filtration; rheology; grouting phase;

    Abstract : 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. READ MORE

  6. 5. Grouting Design Considering Different Geological Conditions : Grout evaluation for the extension of the Blue Metro Line

    University essay from KTH/Jord- och bergmekanik

    Author : Roaa Al Omari; Yasmeen Alali; [2021]
    Keywords : ;

    Abstract : This thesis forms the basis for a new documented experience of grouting design and work in the extension of the blue metro line in Stockholm. It includes documentation of the grouting design based on theoretical basis, stop criteria and fan geometries for favorable and unfavorable geological conditions. READ MORE
