CEEN 641 – ADVANCED SOIL MECHANICS HOMEWORK ASSIGNMENT #12 1. Five feet of water overlies a uniform profile of soil. The soil has a saturated unit weight of 127.4 pcf and the shear strength parameters indicated below: CD triaxial test CU triaxial test φ 30° 16° c 60 psf 440 psf Determine the shear strength along a horizontal plane at a depth of: a. 5 ft based on a total stress analysis b. 5 ft based on an effective stress analysis 2. A heavy building foundation is to be constructed very quickly on a very thick stratum of saturated, normally consolidated, highly plastic clay. In assessing the stability of the

Unformatted text preview: foundation, identify the type of stress analysis (effective or total) and which type of triaxial test (CD, CU, or UU) you would conduct. Explain your rationale in detail. 3. You are asked to assess the stability of an old embankment dam constructed of a low permeability soil. Identify the type of stress analysis (effective or total) and which type of triaxial test (CD, CU, or UU) you would conduct given the following scenarios. Explain your rationale in detail. Scenario A: Slope stability under steady-state seepage conditions. Scenario B: Slope stability during an earthquake....
