Root-soil composites indoor test and simulation data

Straight shear test data is used STSJ-5A intelligent electric quadruple straight shear instrument, in the positive pressure of 100 kPa, 200 kPa, 300 kPa, 400 kPa conditions to set the test rate of 0.8 mm/min, shear test, read the displacement meter display, recorded every 10 s, each specimen shear 5 minutes to get.Numerical simulation model before and after set y-direction displacement constraints, left and right limit x-direction displacement left and right, bottom limit z-direction constraints, the top of the slope, the bottom of the slope and the slope surface are free surfaces, and the model adopts the Moore-Coulomb yield criterion.
