Physical Modeling of Horizontal Force on the Inland Vertical Structure by Tsunami-like Waves

摘要

The tsunami flood the coastal cities and damage the land structures.The study on wave pressure and force on land structures is one of the important factors in designing the stability of inland structures.In this study,two - dimensional wave flume tests on the horizontal wave force and pressure of tsunamis on a simplified box-type structure was conducted.Vertical distribution and wave power of horizontal wave pressure over time were measured by pressure sensors and force transducer.Also,those were measured from the different wave breaking types.The vertical distribution of horizontal wave pressure was uniform at the moment when the horizontal wave force to the structure was maximum under the breaking wave condition.A surf similarity parameter was employed in order to figure out the relationship between the maximum horizontal wave force on the structure as a function of various incident wave conditions.As a result,the non - dimensionalized horizontal wave force tends to decrease exponentially as the surf similarity parameter increases.
