Question

Use the attached measurements of torque-rotation to evaluate the VST, and whatever additional information provided (if you need them) to determine the corrected peak undrained shear strength at 11.1m.

Vane dimensions: d = 55 mm and H = 110 mm. Thickness: e = 2 mm.

Vane in this problem D 55 mm gwt0 m (assumed) ● 5.1 m ● 8.0 m H-110 14.2 m The profile seems to be mostly homogeneous but I still divided it into 4 layers to calculate the in situ effective vertical stress Data in italic 14.2 78.18327 84.72 74.53 83.9 312 2.69 11.1 Depth 055 m 0.110 m Wn 95.2 44.7 2.72 93.8 39.4 2.7 45 2 2.66 PL RotationTorque Torque Torque Torque N-m 0.0 0.2 0.5 0.7 1.0 0.0 3.2 6.3 9.7 12.5 15.1 18.2 20.7 0.0 4.7 9.5 4.5 18.6 22.7 25.9 31.1 0.0 5.7 114 17 4 0.0 3.5 6.9 84 9.6 115 13.1 13.8 12.2 9.8 8.1 272 31.1 37.4 42.5 44.6 44 8 38.4 26.2 1.7 2.4 23.9 24.8 19.4 14.6 37.1 33.0 26.3 21.8 4.7 6.5
