Comparison of time-dependent viscosity slurry and cement-clay slurry for anti-seepage grouting on faults

open access: yesFrontiers in Earth Science, 2023
The complex rock mass structure in fault fracture zone weakens the permeability of strata. This has led to curtain grouting being used to improve the anti-seepage properties of fault zones.
