【摘要】 杭州湾大桥于浙江省慈溪市横跨杭州湾,全长36km,为迄今已建与在建的世界最长的跨海公路桥梁。以实测资料分析为基础,数学模型提供设计边界条件,实体定床与动床模型为主要手段,探讨了建桥对水环境的影响,得出了杭州湾大桥的建设对水流的影响较小、且主要发生在桥位近区,对钱塘江涌潮基本没有影响,对上游泄洪无负面影响,对乍浦港与南北航道无明显不良影响的明确结论。更多还原

【Abstract】 Acrossing the Hangzhou Bay from Zhengjiadai at the Haiyan county to the shuiluwan at the Cixi city, the Hangzhou Bay Major Bridge is 36km long. It is the longest bridge of acrossing sea over the world. Based on analyzing the observed data and providing the design boundary conditions by the mathematical model, the influence of the Hangzhou Bay Major Bridge on the water environment was studied using the fixed bed model and mobile-bed model tests. After building the bridge, the influence of the bridge to the flow is less and mostly nearby the bridge, and to the tidal bore and the flood is slight in essence, and to the Zhapu port and navigations is less also.更多还原
