| 摘 要： | 长江对武汉市三大市区的交通影响很大,城市发展,过江交通日益拥塞。为解决这一问题,长江第一隧道现正设计、施工。在隧道工程定床河工模型试验的基础上又进行了动床模型试验,目的是研究隧道对河势、河床冲淤、洲滩变迁、流速分布、主流摆幅等的变化影响,以及隧道断面处的冲刷深度,为隧道工程安全和设计决策提供科学依据。

| Abstract: | The first tunnel drilling project under the Yangtze River is being carried out,in order to solve the problem of congestion of communications on Yangtze River in Wuhan.The movable-bed model test is designed to study the variations of river regimes,scour-accretions of river bed,fluvial processes,flow velocities,flow patterns and erosions of the tunnel cross-section.Reliable results are obtained,and a preliminary basis for tunnel design is provided. |
