摘要

Abstract

Accurate estimation of wave uplift force is essential to the designs of reliable coastal and marine structures. We presents a series of laboratory work here on the impact of regular waves on horizontal panels

from which an empirical formula to estimate accurately the wave uplift force on panels is established. The laboratory measurements show that the wave uplift force depends mainly on the incident wave height

the wave period

the wave length

the panel width

and the clearance between the subsurface of the panel and the still water level. Among these factors

the impact of the panel width on uplift forces is relatively complicated. Result shows that the relative panel width (i.e.

the ratio of panel width to wave length) plays a more important role in estimating the wave uplift force. Based on our comprehensive laboratory measurements

we further developed an empirical formula to compute wave uplift force on horizontal panels through dimensionless analysis. Compared with other empirical formulas

this formula uses dimensionless variables of clear physical meanings

thus can describe the interaction between waves and the panels in a better way. In addition

the efficiency of the formula to estimate wave uplift force on horizontal panels is verified against existing works. Therefore

the findings in this study shall be useful for understanding the mechanism of wave uplift force on horizontal panels and numerical model validation.
