Width of the test pit for plate load test is made five times the width of the plate

At the centre of the test pit, a hole is dug out whose size is kept equal to the size of the test plate

Bottom level of the hole dug at the centre of the test pit, is kept at the level of the actual formation

All the above.

soil is homogeneous and isotropic

elastic zone has straight boundaries inclined at ψ = φ to the horizontal and plastic zones fully developed

failure zones do not extend above the horizontal plane through the base of the footing

all the above
