Implication

Assessment reveals that varying slurry viscosities and pressures significantly impact filter cake permeability, suggesting optimal conditions for construction safety.

Key Points

Higher viscosity slurries lead to lower filter cake permeability, which is crucial for excavation stability.
At 25 and 40 kPa, low-viscosity slurries show permeability values of 2.68 × 10−5 and 4.64 × 10−5 m/s respectively, but this decreases at higher pressures.
Bentonite slurries with viscosities of 2253.89 and 6.81 mPa·s were tested under pressures ranging from 25–70 kPa to ascertain permeability effects.
Using low-viscosity slurries at elevated pressures may enhance construction efficiency and safety in underground projects.
