PORE AND ERODING FLUID INFLUENCES ON SURFACE EROSION OF SOIL-CLOSURE

Comments are made regarding the influence of the pore fluid composition on soil structure, the dispersion-cohesion boundary and the Pinhole Test, and determinations of the critical shear stress of core samples. It is noted that different clay minerals have different boundary curves, which is presumably a factor in the width of the "Dispersive or Nondispersive" band. The uncertainity inherent in the Pinhole Test is also a factor which contributes to the band of uncertainity. This test is an empirical test based on subjective evaluation of the occurrence of dispersion, and its use to evaluate the critical shear stress on soil is inaccurate. The rotating cylinder test, using loss of weight as a measure of erosion, provides accurate determinations of the critical shear stress of core samples or remolded samples of cohesive soils, so long as vertical variations in soil properties are not significant over the length of the sample.
