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. 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

   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

5. 4. Experimental Evaluation of the Effects of Dynamic Pressure on Improving Cement-based Grout Penetrability : A study performed with the short slot

   University essay from KTH/Jord- och bergmekanik

   Author : Anastasios Mentesidis; [2015]
   Keywords : penetrability; filtration; erosion; cement-based grout; variable dynamic grouting;

   Abstract : The increasing need for watertight underground works, such as tunnel excavations, has sparked an interest in a number of research studies with grout penetrability being the focus. The research has so far contributed to a deeper understanding regarding the assessment of a successful grouting operation from different perspectives such as choice of equipment, material properties, phase planning and performance.

6. 5. Evaluation of the Grouting Methodology used in the Stockholm City Line Project

   University essay from KTH/Jord- och bergmekanik

   Author : Brynjolfur Brynjolfsson; [2014]
   Keywords : Stockholm City Line; Citybanan; Grouting; Pre-grouting; Pumping time;

   Abstract : As part of the Stockholm City Line project a grouting design was conducted and documentedduring the planning phase, based on theoretical grounds. This comprehensive design is the first of its kind for a tunneling project in Sweden. READ MORE
