Direct shear test
Direct shear test
(OP)
Hello
Our technician conducted Direct Shear box test on samples i gave him , the test is conducted with three normal Stresses (1 ,2 ,3 bars )
Thing is i find that sometimes the shear resistance of the sample for say 1 bars is greater than that of 3 bars or you may find the 3 bars shear strength in the middle between the other two !
how can we explain that ?

problem is the odometer test concluded that it is over consolidated.
@Fattdad its a saturated clay with low plasticity , test is conducted until a stress of 5 mm is reached
the strain rate is 1 mm/min

i am guessing that the sample was modified during preparation

Grading modulus ? as in soil sieve analysis ?
tbh i never verify my samples so does all engineer here but i will from now one , the guys at the lab can ruin samples for sure
