摘要
确定桥区水域范围是保证通航船舶和桥梁安全的一个重要因素,但是目前国内外对于如何划分桥区水域的大小并没有明确的标准。以港珠澳大桥为研究对象,从桥梁的有效航宽、拖轮施救时间和船舶失控危险区域三个方面计算了桥区水域尺度。通过对各种工况的计算比较,得出港珠澳段桥区水域尺度为桥梁两侧各2 n mile。
It is an important factor to determine the range of bridge water area to guarantee safety of ship navigation and bridge.However,there is no clarified standard in China or abroad for setting the range of bridge water area at present.Taking Hong kong-Zhuhai-Macao Bridge as an object,the range of the bridge water area is calculated in three aspects： bridge＇s effective width for navigation,rescuing time for tugboat and dangerous area of out-of-control ships.It is obtained that the bridge water area should cover 2 n miles on each side of the bridge.
