On the physical meaning of equivalent skeleton void ratio for granular soil with fines [PDF]
AIP Conference Proceedings, 2013 Recent research on the behavior of silty sand usually involves the use of equivalent skeleton void ratio to characterize its packing density state. The equivalent skeleton void ratio is a modified void ratio by the introduction of a parameter b to account for the participation of fines in the force chains. However, the parameter b is poorly understood.
