Theoretical Approaches in Grouting Fractures of the Rock Mass: Theories and Applications
2013 (English)In: 47th US Rock Mechanics / Geomechanics Symposium, American Rock Mechanics Association (ARMA), 2013, 1731-1737 p.Conference paper (Refereed)
Currently there is a great deal of specific attention on improving the grouting methods since optimizing the grouting process will have significant impact on performance and economy of projects as well as safeguarding the purity of nature. The main problem with existing grouting method is lack of knowledge about the spread of grout, i.e. there is no clue if the grout has been penetrated enough or if it has been over spread. Also the state of fractures during grouting is unknown. In the last decade, theoretical approach has been developed which enables estimation of the grout spread in real time. Furthermore, by replacing the estimated penetration length with injected volume, dilation of the rock fractures is monitored in real time. In this paper, this analytical solution has been examined and competency of its application has been discussed. Implementing this theory with data from City Line project confirms the usage of high applied pressure in this project which will lead to shortening of the grouting time.
