为了适应迅速增长的旅客和航空货运业务需要,使日本航空业早日更多进入有利可图的国际航运市场,日本从1987年开始在关西附近的海面修建规模宏大的关西国际机场。日本政府开拓这个项目的规模是史无前例的,他要在远离本土5公里处、深达18～20米的海水中,修建一个4公里长、1.25公里宽的人工岛屿。之所以选址在这波涛浩翰的大海之中建造这么巨大的海洋工程,主要是为了避免机场上飞机起降的噪音干扰居民区的宁静,使飞机在一天24小时里都能飞行。
In order to meet the needs of the rapidly growing passenger and air cargo business and to allow Japan’s aviation industry to enter the profitable international shipping market sooner or later, Japan started building the Kansai International Airport on a large scale near the sea of Kansai from 1987. The scale of the Japanese government’s pioneering project is unprecedented. He plans to build an artificial island 4 kilometers long and 1.25 kilometers wide at sea depths of 18 to 20 meters 5 kilometers away from home. The reason why the siting is so large in the vast sea is to build such a huge marine project mainly to avoid the noise of landing and landing on the airport from interfering with the tranquility of the residential area so that the aircraft can fly within 24 hours a day.
