近些年来,世界各地斜坡式防波堤遭受强风浪袭击而损毁的事故屡屡发生,其中尤以1978年2月葡萄牙sines港使用大型工字块体斜坡堤的损毁最为严重。为此,引起了欧美各国工程界的重视,相继组织了实地调查和学术讨论会,并发表了许多有关sines防波堤大型工字块体损毁原因及防治方法的 In recent years, slopes of breakwater around the world have suffered frequent damage due to strong winds and waves. In particular, the use of large blocks of block slopes in sines port of Portugal in February 1978 has caused the most serious damage. For this reason, it has drawn great attention from the engineering circles in Europe and the United States, and successively organized field surveys and academic symposiums and published many reasons and prevention methods for the damage to the large block of sines breakwater
