Design a pile group consisting of RCC piles for supporting a column of size 750×750mm carrying a total load of 2000 kN. The site exploration data reveal that the sub-soilconsists of a deposit of clay extending to a great depth. The soil deposit has acompression index of 0.10 and an initial void ratio of 0.9. Also, the soil is having asaturated unit weight of 21 kN/m³ and an unconfined compressive strength qu of 80kN/m?. The water table is at the ground level. The factor of safety 2.5 shall be usedagainst bearing and the value of adhesion factor as 0.7. Proportion the pile group forthe permissible settlement of 40 mm also design the pile group by considering bothbearing and settlement criteria.

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?
