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.

A channel has been designed to convey clear water to a fish hatchery. The design calls for aflow depth of 2.0 ft and a velocity of 2.0 ft/s. The channel is very wide so the side effects canbe neglected and the hydraulic radius taken as equal to the depth. It is to be constructed insand which has a median diameter ds = 0.915 mm (0.003 ft). For a flat bed in this materialthe Darcy-Weisbach friction factor is estimated to be f = 0.0185 and the required channelslope is S = 0.000145. The water temperature is 20°C and the kinematic viscosity υυ is = 1.08x 10-5 ft2/s. The specific gravity of the sand is 2.65. Clear water is admitted to the channeland it is imperative that no material be scoured from the bed since any sand in the hatcherywill result in instantaneous death of all the fish. Using Shields' diagram, determine if theexisting design is adequate to deliver clear water to the hatchery.
