Abstract To study the mechanism of silica sol imbibition grouting for mud-bearing low-permeability rock，imbibition tests were carried out on two low-permeability artificial cores. The microscopic seepage characteristics during the imbibition grouting process of the low-permeability cores were tested based on the low-field nuclear magnetic resonance(NMR) system，which revealed the pore filling and closure patterns from the microscopic scale. The injectability of silica sol to low-permeability rock was analyzed in combination with core pore size distribution and silica sol-gel growth law，and the mechanism of silica sol imbibition grouting and engineering application prospects were discussed. The results show that silica sol has an outstanding ability to absorb and infiltrate low permeability cores，with an affinity of 92.2% of that of deionized water. The absorption curve of silica sol is characterized by exponential three-stage distribution，in which the absorption process of 0.1 mD core is mainly controlled by micropores while the absorption of 20 mD core is successively controlled by mesopores and micropores. The characteristics of nano-pores and the growth of silica-sol gel have significant effects on the injectability of silica-sol imbibition，and the injectability and capillary force jointly affect the results of absorption. Silica sol imbibition grouting can meet the engineering requirements of nano-scale pore-fracture sealing in the low-permeability rock mass.

Key words： rock mechanics low permeability rock silica sol NMR pore characteristics imbibition grouting injectability
