Discussion of 'Comparative study of Y-shaped and circular floating piles in consolidating clay'.

The article critiques the research that estimates the skin friction of piles which is embedded in consolidating clay and states that cohesion of saturated clay was not considered in the calculation method. Topics include the empirical methods used to predict skin friction of pile, and calculation of unit limit fs using numerical methods. It mentions graphs on the relationship between shear strength and depth of clay surface.
