Test for Determination of Shear Strength

The term shear strength is often associated with the soil. Shear strength is defined as the resistance to the deformation of soil particles due to the continuous action of shear stress. In short, shear strength is the maximum shear stress that a soil can sustain.

Question

Separate triaxial compression tests are performed on identical soil samples. The soil is saturated mixed soil. At failure, the respective minor and major principal stresses values are 10 kPa and 30 kPa for sample one, and 40 kPa and 70 KPa for sample two. From these data, determine the value for ∅ and the cohesion intercept C on the Mohr’s circle shear strength coordinate. Show all hand calculations and diagrams.

Question-3:(i). For the given failure surface, determine the factor of safety in terms of total stress for the slope given in the Figure 01. The unit weight for both soils is 19 kN/m3. The characteristic undrained strength (cu) is 30 kN/m2 for soil 1 and 45 kN/m2 for soil 2. What is the factor of safety aginst slope failure?(ii).

Separate triaxial compression tests are performed on identical soil samples. The soil is a saturated mixed soil. Both tests follow the procedure for consolidated–undrained conditions. At failure, the respective minor and major principal stress values are 20 kPa and 46 kPa for sample one and 40 kPa and 80 kPa for sample two. From these data, determine the value for fCU and the cohesion intercept c on the Mohr’s circle shear stress coordinate. (This problem can be solved graphically using the Mohr’s circle.)
A cut slope in soft clay has been constructed as part of a road alignment. The slope is 21.8 degrees and 10 m high. The unit weight of the soft clay is 18kN/m3. (i) A walk over survey recently indicated signs of instability. Samples have been collected from the slope and the drained analysis parameters for the soil have been determined as follows: Soil properties: φ'= 24 º, c'=2.5kPa, γd=19kN/m3 , γsat=20kN/m3 Based on the effective stress parameters given, perform a quick initial estimate of the factor of safety of this slope using Bishop and Morgernsterns charts.

A geotechnical engineer is evaluating the stability of a silty sand slope as shown. This evaluation is considering the potential for a shear failure at an infinitesimal point (soil element) on the trial shear surface.

(Plot the Mohr circle) (B) If the silty sand is found to have a cohesion of 250 kPa and a friction angle of 25 deg from direct shear (DS) testing, plot the failure envelope against the same pole-method graphical construction completed under question above.
