| Abstract: | Circular cylindrical piles are commonly used structural members in marine applications. When these piles endure sustained exposure to a marine environment, corrosion deposits and marine organisms accumulate on their surfaces. The subsequent increase in surface roughness would be expected to influence the friction, form and inertia drag characteristics of the pile when subjected to wave action. This influence, in turn, would be expected to have an effect on the magnitude of the force developed on the pile. Apparently, no previous attempt has been made to evaluate the effects of surface roughness on wave forces developed on piles when subjected to the nonsteady flow conditions inherent in wave motion. This dissertation is an attempt to help fill this void in the literature so that marine structural installations may be more satisfactorily and economically designed. ... |
