| 摘 要： | 从定、动床试验及环境保护进行分析研究。定床试验:研究工程实施后,本河段的水位,流速、流态及天兴洲左右汊分流比的变化;动床试验:研究在不同典型水文年条件下的河势、河道冲淤变化及疏浚区的回淤问题,为治理方案的比选优化及工程决策提供科学依据。这是长江干流滨江城市河道整治的先声,是城市规划建设中环境保护工程实施的首例,意义重大。其环境、社会及经济等效益也将十分显著。

| Abstract: | The author analyzes and studies by the experiments of immovable and movable bed,integrating the knowledge of the water environment protection.By the immovable bed experiment,the change of the water level,velocity,flow shape and diversion ratio between the left and right braided channel in Tianxingzhou is researched after the project actualized;by the movable experiment,the river regime,the channel change of scour and sedimentation and the back deposition problem of the dredged region are studied in different and typical hydrology-year.The researches provide the scientific groundwork for the scheme choice and decision-making of the project.As it is not only a start of the mainstream channel regulation along the Yangtze River,but also the first example of carrying out water environment protection in the urban programming and construct.The environment,society and economy benefit is very obvious and the meaning is significant. |
