Problem Solving. Answer the following problems and box your final answer. Use short bond paper for the solutions.
1. A cohesive soil has an angle of shearing resistance of 15o and a cohesion of 30 kN/m2. A specimen of this soil is subjected to a tri-axial compression test.a) Find the deviator stress of failure.b) The normal stress at the failure plane.c) What is the sp.gr. of soil if the shear strength at the failure plane is located at a depth of 5m.
The void ratio is 0.6.
2. The following data was recorded during an undrained tri-axial compression test on a clay soil.Cell pressure (kPa) 100 250 400Deviator stress at failure (kPa) 320 425 530Pore pressure at failure (kPa) -33.5 53 140Compute the following:a) Undrained value of shear resistance, cu.b) Drained value of cohesion, C.c) Compute the shearing strength of drained soil at a depth of 4m, if the degree of saturation is
82% with a water content of 12%. Sp.gr. of soil = 2.6.
