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.

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。

The similarity scales can be deduced by using the plane two\|dimensional (2D) unsteady flow equation of momentum and continuity. Laoyancang and Jinshan are selected as the upstream and downstream boundaries. Total simulation area is about 2 200 km\+2. The physical model moulded to the underwater charts of September 2000 is verified with hydrometic data at the same time. The graphs of tidal level and the velocity in the model are conferming with the prototype. The verification has reached a higher accuracy, so...

The similarity scales can be deduced by using the plane two\|dimensional (2D) unsteady flow equation of momentum and continuity. Laoyancang and Jinshan are selected as the upstream and downstream boundaries. Total simulation area is about 2 200 km\+2. The physical model moulded to the underwater charts of September 2000 is verified with hydrometic data at the same time. The graphs of tidal level and the velocity in the model are conferming with the prototype. The verification has reached a higher accuracy, so that the reliable base for the research on the influence of the Hangzhou Bay Major Bridge and the optimization of axes of the bridge is established.

根据平面二维非恒定流运动方程和连续方程推导出模型相似比尺,从而进行模型设计。模型上边界选在老盐仓,下边界定在金山,模拟总水域面积约2200km2;模型先按1998年实测的准1∶50000水下地形制作,并利用1998年大范围水文资料作初步验证,再运用2000年9月杭州湾实测水下地形及大范围同步水文测验资料对模型进行正式验证。验证结果表明,模型沿程潮位、模型测点流速、流向等均与水文测验资料吻合良好,达到了较高的验证精度,为杭州湾跨海大桥建成后对周围水域变化情况的预测和桥轴线与桥孔布设合理性论证奠定了坚实的基础。

The influence on the flow of the bridge pier, which is situated in non\|navigable opening of the Hangzhou Bay Major Bridge, is analyzed by using the physical model of the cross section, in which both horizontal scale and vertical are 100. Two schemes are compared in the experiment. One is that the bridge span is 50 m and 7 spans are arranged in the model. The other one is that the bridge span is 70 m and 5 spans are arranged. In order to reflect the influence on the flow of the different...

The influence on the flow of the bridge pier, which is situated in non\|navigable opening of the Hangzhou Bay Major Bridge, is analyzed by using the physical model of the cross section, in which both horizontal scale and vertical are 100. Two schemes are compared in the experiment. One is that the bridge span is 50 m and 7 spans are arranged in the model. The other one is that the bridge span is 70 m and 5 spans are arranged. In order to reflect the influence on the flow of the different bridge pier, 16 measuring points of velocity and 4 survey stations of water level are arranged in the model. The experimental result shows that the change rates of the flow velocity are both within 9%, and the change values of water level are both within 017 m. Relatively, the influence of the bridge pier with the 50 m's span is slightly bigger. But the biggest difference of the 2 change rates of the flow velocity is only 16%, and the biggest one of 2 change values of water level is 003 m. So the influence ranges on the flow of 2 kinds of the bridge pier are rather close. This result basically conforms with the conclusion of the physical model for the Hangzhou bay major bridge. Saving huge investment and constructing conveniently, the scheme of non\|navigable opening with 50 m's span is recommended and adopted.

利用水平比尺与铅直比尺均为100的正态断面模型,研究了杭州湾跨海大桥非通航孔两个桥跨的桥墩对水流的影响。方案一为50m跨径的桥墩方案,在模型中布置了7跨6个桥墩;方案二为70m跨径的桥墩方案,在模型中布置了5跨4个桥墩。在桥位附近的不同距离处还布设了5条断面16个流速测点和4个水位测站,以反映不同桥墩对周围环境的影响,结果表明,两个方案的流速变化率均在9%以内,水位壅高值在0.17m以内。相对而言,方案一对水流影响稍大,但两方案的流速变化率最大差异仅为1.6%,水位变化最大差异为0.03m,与杭州湾跨海大桥整体模型的试验结果基本一致。由于两个方案对水流的影响均在同一量级,且50m跨径的桥墩可以节省巨额投资,又便于施工,因此,建议杭州湾跨海大桥的非通航孔采用50m跨径。
