海洋浮式结构物

2016-03-21 16:10:25   观察者网

日本国土狭窄,平原面积小,人口众多,具有很长的海岸线和许多远离本土位于太平洋中的小岛。根据联合国海洋法,日本拥有451平方公里的海洋专属经济区,是日本本土面积的12倍。因此,日本政府历来十分重视海洋资源的开发和利用。日本于1973年为建造关西国际机场,提出KIA计划,进行大型海洋浮式结构物作为浮动机场的可行性研究。KIA前期计划的浮动机场由主跑道和辅助跑道组成,主跑道长5000米、宽840米,辅助跑道长4000米、宽410米。采用的是半潜式结构。KIA后期计划与前期计划相比最大的差别就是采用了箱型结构型式,以降低建造成本。为了改善其在波浪中的运动特性,在超大型海洋浮式结构物外围设置了一道防波堤。1999年8月4日,日本在神奈川县横须贺港海面上建成了一个海上漂浮机场。这个海上漂浮机场是1995年开始研制的,它由6块长380米、宽60米、厚3米的模块焊接而成,有一条1000多米长、最宽处达120米的起降跑道。该机场于2000年进行飞机起降试验,成功后将其拆除。该机场具有很大的军事价值,战时可以作为支援作战飞机的移动基地使用。

美国自第二次世界大战后,为了维护其世界霸主地位,建立了一个遍布世界各地的海外军事基地网,沙漠盾牌、风暴行动表明,作战部队和军事装备的快速移动性对打赢一场局部战争起到决定性的作用。但近20年来,由于社会、政治和经济等方面的原因,美国的海外基地数量不断减少,功能不断削弱,并且这种趋势还将继续下去。因此美国工业界、学术界和政府有关部门的专家认为必须利用高技术,发展一种可快速布置到预定海域的海上后勤基地,以减少对海外基地的依赖。1992年美国国防部从其预算中拨出专款进行可移动式离岸基地MOB(themobileoffshorebase)的研究,MOB是一种多功能、可安置在近海或国际水域的浮动的后勤基地,它是由可自航的若干模块在海上拼装而成,可以为固定翼战斗机和直升机提供跑道。除此之外,由美国国家科学基金会资助夏威夷大学实施超大型海洋浮式结构的研究计划。

此外,英国也有过利用大型浮式结构物在原有机场旁建设新跑道的规划。
