Plagiarism will be penalised severely. 1. (10 marks): This tutorial continues Tutorial No. 4. The soil profile for proposed roadway construction is represented in Figure 1. A soil sample was recovered at A, and was tested in an oedometer device. The test results are provided in Table 1. The void ratio of the...
The results of a laboratory consolidation test on a clay specimen are given in the table The initial height of the specimen is H=19 mm, specific gravity is ?? = 2.68, moisture content is ? = 26%. a. Draw the ? − log ?? ′ (?? ? − log ? ) curve (the student is allowed to plot using spreadsheet) b. Determine the preconsolidation stress Question 1 (40 points): The results of a laboratory consolidation test on a clay specimen...
