Question

True or False:

Q1) During direct shear test, vertical strain is measured while horizontal strain, vertical stress, and horizontal stress are measured.

Q2) Direct shear testing provides the shear strength properties of soils under conditions of undrained loading.

Answer 1

Direct shear test is used to determine the engineering properties of a soil.

The strength parametres obtianed from direct shear test are cohesion and angle of friction.

Normal displacement (Vertical), Relative lateral displacement (Horizontal), Shear force (horizontal) and Normal force (Vertical) are different parametres which are measured during the test...

this test is easy and cheap but it has a serious disadvantage that there is no control of drainge hence only drained test can be done..

Therefore

1) True

2) False
