In view of the fact that the theory of fracture grouting in deeply buried rock strata seriously lags behind engineering practices, a circular fracturing diffusion model of a single fracture was established by considering numerous influencing factors of deeply buried rock strata, such as the crustal stress characteristics, rock mechanical properties, and time-varying characteristics of the serous viscosity.
By setting the stress intensity factor KI equal to the material fracture toughness KIC at the fracture tip as the criterion for fracturing, the diffusion equation for the fracture grouting was derived and verified experimentally.
Theoretical analysis shows that the fracture grouting pressure P0 is linearly proportional to the depth of the strata H and the lateral pressure coefficient k.
The time-varying characteristics of the serous viscosity have an important influence on the grouting pressure and the diffusion radius.
Its early impact is small, while its later impact is large.
The diffusion radius of the grouting is indirectly proportional to the grouting pressure and the grouting flow rate.
In order to increase the diffusion radius of the grouting, the grouting pressure and the grouting flow rate should be increased simultaneously.
In order, the main factors influencing the diffusion radius of the fracture grouting are the time-varying characteristics of the serous viscosity, the grouting pressure, the grouting flow rate, and the depth of the strata.
