杭州湾跨海大桥南航道通航孔通航净空尺度

Evaluation of navigation headroom and breadth limit of south sea-routeon of the Hangzhou Bay Major Bridge

在杭州湾交通通道预可行性研究阶段的《通航标准论证报告》及杭州湾交通通道有关专题研究成果的基础上,依据浙江省交通厅文件的精神,结合杭州湾的水文、河势、港口、航道等基本状况、条件以及通航船舶现状与未来对通航发展的要求等,确定了杭州湾跨海大桥南航道的通航净空尺度和桥位航道中心线及通航孔的位置。在杭州湾南航道中心线设了3个通航孔,其中1个为主通航孔,2个为副通航孔。主通航孔可通行总长为97m,宽为14m的3000t级杂货船,净空高度不于31m,净空宽度不小于125m,单向通航;副通航孔可通行总长小于33m,宽为7.2m的小型船舶,净空高度不小于20m,净空宽度不小于50m,单向通航。最高通航水位为5.19m。

During the researches of the Hangzhou Bay Major Bridge, based on the sufficiency research and evaluation, we put forward the navigation headroom yardstick of south navigation channel and the navigation channel central\|line, which provide an important basis for the design of the Hangzhou Bay Major Bridge.
