1. A dilatometer test was conducted in a sand deposit at a depth of 6 m. The ground- water table was located at a depth of 2 m below the ground surface. Given, for the sand: gd 5 14.5 kN/m3 and gsat 5 19.8 kN/m3. The contact stress during the test was 260 kN/m2. Estimate the soil friction angle, f9.
2. The P-wave velocity in a soil is 105 m/sec. Assuming Poisson's ratio to be 0.32, calculate the modulus of elasticity of the soil. Assume that the unit weight of soil is 18 kN/m3.
