Which of the following is a disadvantage of shear box test a) explanation: in direct shear test, the stress condition across the soil sample are very complex. Shear box test of soils – procedure in the shear box test, failure is caused in a pre-determined plane of the soil, the shear strength or shearing resistance and the normal stress both being measured directly, as it is a direct shear machine. The object of this test is to determine the shear parameter of soil with the help of shear box the properties with enable soil to maintain equilibrium on a sloping surface is known as shear strength of soil. Direct shear test soil mechanics the main advantages and disadvantages of shear box test e) reliability of the results and the factors most likely to influence.
