A constant head permeability test has a soil sample length in the direction of flow of 350 mm, a sample cross sectional area normal to the flow direction of 125 cm2, and a head loss through the sample of 420 mm. The soil sample is a medium dense sand with a void ratio of 0.61. During a 3 minute test period, 580 cm3 of water flowed through the sample. (a) Sketch the Constant Head Permeameter and label the sketch with the appropriate dimensions given above. (b) Determine the Hydraulic conductivity, k, in cm/sec, and the seepage velocity (not just apparent velocity).

A series of direct shear tests has been performed on a dense well-graded sand. All tests were performed on 3.00-in. diameter, 1.25 in. tall cylindrical samples, and were run slowly enough to produce drained conditions. The results of these tests are summarized in the following table: Test Number Normal Load (lb) Shear Load at Failure (lb) 1 100 84 2 200 159 3 400 319 Assuming the shear area remains constant during the test, determine the effective cohesion and effective friction angle from these test results. What values of these parameters would you expect? Are the test results consistent with your expectations? What values would you use for design?
