Unformatted text preview: Solution of Homework No.6 CEE 330 Fall 200910 Date: November 5, 2009 Problem 1: The major principal total stress ( 1 ) on a specimen is 225 kPa, the minor principal stress ( 3 ) is 150kPa, and the pore pressure (u) is 50kPa. (a) Plot the Mohrs Circle for effective stresses. 2. An isotropically consolidated undrained triaxial compression (CIUC) test was performed on a 152mm long clay specimen at the in situ vertical effective stress of 75kPa. Processed data for axial displacement, minor principal total stress ( 3 ), major principal total stress ( 1 ), and pore pressure (u) are included in the spreadsheet (triaxial_data.xls). (a) Plot the Mohrs circle at failure. Failure is defined as the maximum principal effective stress ratio, ' 1 / ' 3 , also known as maximum obliquity. When pore pressures are unknown, failure is defined at the maximum principal stress difference ( 1 3 ). For the data in this problem, those points are coincident, and are also the last point in the data set. (b)...
