一、引言随着人类对海洋石油及矿藏开发的需求日益增长,近年来海洋工程在世界各国得到迅速发展.我国拥有漫长的海岸线和宽广的大陆架,海域辽阔,资源丰富,大量有关海洋工程科学的课题有待我们去研究与解决.海洋结构动力学主要研究波浪与海工结构的相互作用,结构与海底地基的相互作用,提出合理、实用的结构分析的数学模型、理论与方法,解决结构振动响应、强度计算和 I. INTRODUCTION With the increasing demand of human beings for the development of offshore oil and mineral reserves, marine engineering has rapidly developed in various countries in the world in recent years. China has a long coastline and a wide continental shelf. It has vast sea areas, abundant resources, and a large number of related marine engineering science. The subject remains to be studied and solved. Marine structural dynamics mainly studies the interaction between wave and marine structure, and the interaction between structure and submarine foundation. It proposes a mathematical model, theory and method for reasonable and practical structural analysis, and solves the structural vibration response. , intensity calculation and
