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

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Zhuohang Lian; [2022]
   Nyckelord :Rock engineering; Rock grouting; Variable injection pressure; Dynamic grouting technique;

   Sammanfattning : 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

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

   Master-uppsats, KTH/Jord- och bergmekanik

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

   Sammanfattning : 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.
