Abstract
Residual soils are known to undergo strength loss when unsaturated soils are soaked. This study looks at the nature of such strength loss for both disturbed and undisturbed samples of a local soil as determined in the direct shear apparatus. Remoulded and undisturbed samples of a local soil were tested both soaked and unsoaked in the direct shear apparatus under vertical consolidation pressures ranging from 20kPa to 320 kPa. The effect of the soaking on the strength as defined by the maximum shear stress and the parameters c and φ are compared and discussed. The results are discussed in terms of unsaturated soil mechanics principles.
