Paper presented at the 51st U.S. Rock Mechanics/Geomechanics Symposium, June 25โ€“28, 2017
Paper Number: ARMA-2017-0269
... ABSTRACT: Grouting of rock fractures is an effective way to reduce or prevent water inflow during rock excavation. Prediction of the grouting process can greatly optimize the corresponding grouting progress and reduce the relevant cost. The theoretical model for grout flow between parallel...

Paper presented at the 44th U.S. Rock Mechanics Symposium and 5th U.S.-Canada Rock Mechanics Symposium, June 27โ€“30, 2010
Paper Number: ARMA-10-252
... behavior model is used to simulate the grout having two components namely yield stress ( 0 t ) and viscosity (ยต) but practically the viscosity parameter is ignored to compute the grout penetration length. Furthermore, the grout flow is presumed as a steady state flow and then after satisfying stopping...

Paper presented at the 44th U.S. Rock Mechanics Symposium and 5th U.S.-Canada Rock Mechanics Symposium, June 27โ€“30, 2010
Paper Number: ARMA-10-331
... ABSTRACT: The grout flow through rock mass discontinuities has usually been simulated with a laminar flow. In the laminar flow through a micro-channel, however, the flow is significantly dependent on the roughness of the channel surfaces. The effect of the joint roughness coefficient (JRC...
