SUBGRADE REACTION TO CAISSON IN COMPOSITE-TYPE BREAKWATER REINFORCED BY EMBANKMENT

Evaluation of Vibration Characteristics of Caisson-Type Breakwater Using Impact Vibration Tests and Validation of Numerical Analysis Model

In this study, ambient and forced vibration tests are proposed to evaluate dynamic characteristics of a caisson-type breakwater including natural frequencies and modal damping ratios, and the feasibility of numerical analysis model with fluid-structure-soil interaction effects, which plays an important role to evaluate structural performance and safety, is investigated by comparing the numerica...

A numerical simulation on seepage-induced collapse of caisson breakwater using a stabilized ISPH method

The clarification on the collapse mechanism of a caisson breakwater has been an urgent task in order to reduce damages caused by next millennium tsunamis. In this study, piping destruction of a mound induced by seepage flow is taken into consideration solely. A stabilized ISPH method proposed by Asai (2012) is adopted with some modification associated with the extended Darcy law (Akbari 2013, 2...

The Expected Sliding Distance Model of Meandering Damage for Caisson Breakwater

In the past decades, many references have studied the mechanics of meandering damage for breakwater. However, up to the present time, no model has been proposed to compute the consequence of this kind of damage quantitatively. So, this paper tries to solve this problem by combining the expected sliding distance technique and the diffraction model. 1 Preface The meandering damage of breakwater i...

Numerical Simulation of Wave Overtopping Over Composite Berm Breakwater

Breakwaters have changed a lot during their design history. Overtopping is an important parameter that its evaluation and reduction has always been noticed. In this study, the wave overtopping of composite berm breakwater as a new conceptual structure has been investigated numerical modeling was performed using FLOW-3D software. Then, based on  a laboratory model conducted by Losada et al, cali...
