A rock storage pile is being designed for a mine in West Virginia. The pile is lined with 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 collection stone is being installed. Specify the base slope required to keep the head below 25 cm if the design storm is 0.8 cm rain/day and the pipe-to-pipe lateral spacing is 60 m Is this rock a reasonable material to replace the LCS stone?

Calculation of Settlement

The vertical displacement of the structural foundation due to the loading from the superstructure is known as settlement. It is due to the reduction of air voids present in the soil. The amount of vertical displacement depends on the bearing capacity of the soil on which the foundation is laid. The effect of the settlement depends on the magnitude of settlement, uniformity, and the structural design of the structure. The maximum allowable settlement for residential and office buildings should be less than 18 mm, for industrial buildings, it is 38 mm and for commercial buildings, it is 25 mm.
