Description

一种修建跨海大桥的方法 技术领域
本发明涉及桥梁建设技术领域，尤其涉及一种修建跨海大桥的方法。
背景技术
目前世界上，连接跨水域的方式，就是修建水下隧道或者架设桥梁，如英吉利海峡隧道，丹麦大海峡隧道。后者如庞恰特雷恩湖桥，位于美国路易斯安纳州庞恰特雷恩湖上，连接新奥尔良和曼德韦尔，全长38.4公里，是世界最长的跨水域大桥。
2011年6月30日，青岛胶州湾跨海大桥正式通车。桥梁长36.48公里。成为继美国的庞恰特雷恩湖桥后世界第二长的桥梁。青岛胶州湾大桥位于中国山东省青岛市，为跨越胶州湾、衔接青兰高速公路的一座公路跨海大桥。
被誉为“黄金水道”的琼州海峡是中国的三大海峡之一，东西长度约80公里，南北平均宽度近30公里，不仅是沟通北部湾和南海中、东部的海上走廊，同时也是广东至海南岛和越南等地的海上交通捷径。大桥建成后，驾车跨越琼州海峡只需20分钟，而目前依靠渡轮通过海峡，候船和行船时间约需3小时，经济战略意义重大。
目前，可以说如果水域(江河湖海)的宽度在30公里范围内，人类现有的技术是完全可以建造跨水域大桥，将水域两岸的陆地，连接起来，实现快捷的人流和物流。但是如果水域的距离超过40公里，目前的人类技术很难做到。如果采用修建海底隧道的方法，那么工程造价至少是修建大桥的2倍，而且周期也会变长，海底隧道的地质情况复杂多变，施工难度及其风险巨大。
因此，亟待提出一种方案，可以实现陆地之间较长水域连接通行的建筑设施。
发明内容
有鉴于现有技术的上述缺陷，本发明所要解决的技术问题是提供一种修建 跨海大桥的方法，利用人工岛作为连接水域的中介，在水域中建设一个或者多个人工岛，再在人工岛与陆地之间或者人工岛之间修建大桥，最终实现两个之间有较大水域的陆地的连接通行，其建设周期短，成本相对较低，技术较为成熟，经济效益好，便于推广。
为实现上述目的，本发明提供了一种修建跨海大桥的方法，其特征在于：
S1、包括第一大陆、第二大陆，所述第一大陆、第二大陆之间有海域，所述海域之间修建人工岛，所述人工岛与第一大陆、第二大陆之间建设跨海大桥；
S2、对于距离较大的水域，可以根据距离修建2个或者2个以上的人工岛，人工岛之间、人工岛与大陆之间修建跨海大桥。
上述的一种修建跨海大桥的方法，其特征在于：所述的跨海大桥的直线距离多于30公里。
本发明的有益效果是：
本发明利用人工岛作为连接水域的中介，在水域中建设一个或者多个人工岛，再在人工岛与陆地之间或者人工岛之间修建大桥，最终实现两个之间有较大水域的陆地的连接通行，其建设周期短，成本相对较低，技术较为成熟，经济效益好，便于推广。
以下将结合附图对本发明的构思、具体结构及产生的技术效果作进一步说明，以充分地了解本发明的目的、特征和效果。
附图说明
图1是本发明的海域上修建一个人工岛建设跨海大桥的结构示意图。
图2是本发明的海域上修建多个人工岛建设跨海大桥的结构示意图。
具体实施方式
如图1、2所示，一种修建跨海大桥的方法，其特征在于：
S1、包括第一大陆1、第二大陆2，所述第一大陆1、第二大陆2之间有海域，所述海域之间修建人工岛3，所述人工岛3与第一大陆1、第二大陆2之间建设跨海大桥4；
S2、对于距离较大的水域，可以根据距离修建2个或者2个以上的人工岛3，人工岛之间、人工岛与大陆之间修建跨海大桥4。
本实施例中，所述的跨海大桥4的直线距离多于30公里。
以芬兰湾为例，芬兰湾是波罗的海东部的大海湾，位于芬兰、爱沙尼亚之间，伸展至俄罗斯圣彼德堡为止。芬兰湾面积3万平方千米，东西长约390千米，南北宽50-120千米；因此可以利用本发明的方法修建一个横跨芬兰湾的大桥。
先确定修建跨海大桥的最佳的2点AB(芬兰和爱沙尼亚各一处)，然后在2点之间确定一个点C，作为修建人工岛地址，优选AB的中点作为C点，而且C点处最好有小岛或者暗礁作为修建人工岛的基础。岛身填筑，一般有先抛填后护岸和先围海后填筑两种施工方法。这里选用后一种方法。先围海后填筑适用于风浪较大的海域。先将人工岛所需水域用堤坝圈围起来，留必要的缺口，以便驳船运送土石料进行抛填或用挖泥船进行水力吹填。待人工岛在C建好后，然后将AC和BC修建大桥，其中AC和BC的长度在30公里左右，这样现有的技术完全可以利用，同时可以将人工岛C修建成一个具有人员休息和车辆设备维护维修的物流中心，为过往的车辆提供一个巨大的缓冲区。
其它的海峡如渤海海峡或者台湾海峡也可以使用本方法修建跨海大桥，只是在要修建2个或者更多的人工岛，这样可以修建长度是几百公里的跨海大桥。
本方法具有如下的技术效果：1、能够利用现有技术，修建40公里以上的跨海大桥；2、与修建海底隧道对比，具有工期短，造价可以节约1倍以上，施工容易，避免了塌方等地质风险的发生；3、人工岛可以变成一个具有休息餐饮观光和机动车中转维护维修的物流中心，提高跨海大桥的经济效益，可以缩短投资收回期。
以上详细描述了本发明的较佳具体实施例。应当理解，本领域的普通技术人员无需创造性劳动就可以根据本发明的构思做出诸多修改和变化。因此，凡本技术领域中技术人员依本发明的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案，皆应在由权利要求书所确定的保护范围内。
