-
Well-graded dense saturated sands have high shear strength because :
Whatsapp

|
A.
Such sands have a better grade (superior type) of sand grains resulting in higher strength
|
|
B.
Such sands have lower water content, which increases shear strength
|
|
C.
Such sands have better interlocking of grains, higher inter-particle contacts and higher inter-particle frictional resistance resulting in higher strength.
|
|
D.
Presence of water in such sands induces capillary pressure generating higher inter-granular stresses, which generate apparent cohesion and hence higher shear strength.
