一、前言近年来,在海上人工岛的设计和水域环境保护方面,对防波堤性能的要求及其建设费用都在迅速提高,因此需要采用新的结构型式来适应这一情况。日本运输省港湾研究所,港湾局和港湾建没局等曾就此进行过多种方案的研究。这里将已取得的成果作一扼要介绍。
I. INTRODUCTION In recent years, the requirements for breakwater performance and construction costs have rapidly risen in the design of marine artificial islands and in the protection of water environment. Therefore, a new type of structure needs to be adopted to adapt to this situation. Japan’s Ministry of Transport Harbor Institute, Harbor Bureau and the Harbor built no bureau had conducted a variety of programs on this research. Here are the achievements made a brief introduction.
