Overview

Randomized trial investigates mechanical behavior and failure of sandstone under water immersion, highlighting structural risks.

Key Points

  • This study aims to examine how localized water infiltration affects the mechanical properties and failure modes of black sandstone when immersed.
  • Conducted uniaxial compression tests on black sandstone with varying immersion depths and angles.
  • Assessed compressive strength at different levels of water saturation, highlighting spatial water distribution.
  • Analyzed failure characteristics to determine the impact of immersion angle on rock behavior.
  • Partial immersion results in a nonlinear reduction in uniaxial compressive strength, with 38.9% saturation leading to 88.5% failure strength.
  • Failure transitions from global shear to localized crushing due to stiffness mismatches at wet-dry interfaces.
  • Strength is lowest at an immersion angle of 45°, with recovery noted at 90°, indicating orientation-specific risks.
