A square concrete pile of 10 m length is driven into a deep layer of uniform homogeneous clay. The average unconfined compressive strength of the clay, determined through laboratory tests on undisturbed samples extracted from the clay layer, is 100 kPa. If the ultimate compressive load capacity of the driven pile is 632 kN, the required width of the pile is mm. (in integer) (Bearing capacity factor Nc = 9; adhesion factor a = 1 = 0.7)

A rock storage pile is being designed for a mine in West Virginia. The pile is linedwith reinforced GCL overlain by a 1.5 mm thick HDPE geomembrane. A heavy nonwoven geotextile is placed on top of the geomembrane. Because the rock is porous(K = 10-2cm/s), it is used as the main LCS stone and no additional leachate collectionstone is being installed. Specify the base slope required to keep the head below 25cm if the design storm is 0.8 cm rain/day and the pipe-to-pipe lateral spacing is 60 mIs this rock a reasonable material to replace the LCS stone?
