Grouting during large pressure gradient, such as for post-grouting, remediate grouting of dams are problematic. Typically grout curtains are constructed under dams as a barrier to prevent leakage from the reservoir, reduce uplift, and also prevent transport of fine material through the foundation. This report presents theoretical basis for a grout design for dams; however it is applicable for post-grouting design of tunnels.
The work presented here is part of a PhD study at KTH, supervised by Fredrik Johansson, Liangchao Zou and Johan Funehag and it has also had support from Håkan Stille and a reference group composed of among others Christian Butron, Almir Draganovic, Magnus Svensson, Peter Viklander, Åsa Fransson and Patrik Vidstrand. The research has been co-funded by KTH, Vattenfall, Fortum and BeFo.
