FUNDAMENTALS OF GEOTECHNICAL ANALYSIS

A constant head permeability test is performed on soil that is 2 cm x 2 cm square, and 2.5cm long. The head difference applied during the test is 20 cm and 7 cm³is collected over a time of 100 sec. Provide step by step solution.

a) Compute the permeability based on these test conditions and results.

b) A falling head test is conducted on the same soil specimen at the same time (t1 – t2 = 100 sec), and the standpipe diameter is 0.8 cm. If the average head during the test should be 18 cm, what are h1 and h2 values?
