In order to reveal the characteristics of nano-sized silica sol grout for fractured rock grouting and the temperature effect on the gelation time for nano-sized silica sol grout, the influences of accelerator dosage and temperature on the gelation time were investigated. The results show that the gelation time decreases exponentially with the increase of accelerator dosage and temperature. The gelation time equation of silica sol grout with respect to the temperature effect was proposed. The real-time consistency equation and real-time permeability equation were derived. To design the grouting parameters, the amount of nano-sized silica sol grout and accelerator could be confirmed, and the target penetration length and formation conditions were confirmed. Finally, the grouting pressure was adjusted and the grouting time was calculated.
