Question 1 a) What is the difference between total and effective stress? (10 marks) I b) An undisturbed soil sample containing an effective size 10 of 0.012mm was tested in a falling head permeameter. The results were Initial head of water in standpipe = 1800mm Final head of water in standpipe = 600mm Duration of test = 235 s Sample length = 150mm Sample diameter 100mm Stand pipe diameter = 5mm Determine the permeability of the soil in mis and compare this with Hazen's empirical relationship (10 marks) Question 2 A cylinder of soil has been retrieved from a trail pit for testing in a laboratory The dimensions of the soil sample are 250mm diameter x 400mm. The mass of the sample in its natural state was 35.67 kg, with a specific gravity of 2.67 A small sub-sample was removed to allow the determination of the moisture content. This gave the following results: Mass of wet soil & dish 128.36 gr Mass of dry soil & dish = 103.58 gr Mass of dish 42829 Determine The moisture content The bulk density The dry density The bulk unit weight The voids ratio (10 marks) Briefly describe the common tests which could be used to classify the soil (5 marks) 4301CIVH
