Đánh giá khả năng giảm sóng của kè cọc bê tông có xét đến hình dạng mặt cắt cọc

Abstract

This study evaluates the wave attenuation effectiveness of concrete pile breakwaters with three different cross-sectional shapes (circular, square, and diamond) based on in-situ wave measurements using an ADCP Sentinel-V20. The significant wave height H_s​​​ and maximum wave height H_max were calculated before and after the waves passed through each breakwater type. The results indicate that the square-pile breakwater provides the highest reduction, with approximately 43% for H_s​​​ and 29% for H_max​. The diamond-shaped and circular piles achieve reductions of around 39% and 38% in H_s​​​, with corresponding reductions of 13% and 17% in H_max​. These findings serve as a reference for selecting appropriate pile shapes in coastal protection projects.
