VANE SHEAR TEST

Question 1

It is a widely utilized in-situ
geotechnical testing method
designed to estimate the
undrained shear strength of
saturated cohesive soils,
particularly soft clays.

Answer 1

VANE SHEAR TEST

Question 2

This test is crucial for
understanding soil behavior
under undrained conditions,
which is essential in foundation
engineering and construction
projects.

Answer 2

VANE SHEAR TEST

Question 3
