Figure 6-56: An example of the measured signals (forces and pore pressures).
The result of a cutting test graphically. In this figure the horizontal force Fh, the vertical force Fv and the water
pore-pressures on the blade P1, P2, P3 and P4 are shown. The test is performed with a blade angle of 45, a
layer thickness hi of 70 mm and a cutting velocity vc of 0.68 m/s in the 200 m sand.
