1. Vane shear test is designed to measure the undrained shear strength of very soft and sensitive marine clays. True or False
Answers
Vane Shear Test
OBJECTIVE
To find shear strength of a given soil specimen.
NEED AND SCOPE
The structural strength of soil is basically a problem of shear strength.
Vane shear test is a useful method of measuring the shear strength of clay. It is a cheaper and quicker method. The test can also be conducted in the laboratory. The laboratory vane shear test for the measurement of shear strength of cohesive soils, is useful for soils of low shear strength (less than 0.3 kg/cm2) for which triaxial or unconfined tests can not be performed. The test gives the undrained strength of the soil. The undisturbed and remoulded strength obtained are useful for evaluating the sensitivity of soil.
