【摘要】 本文针对长江下游太平洲捷航道进行研究,得到相应的航道整治方案。采取实地调查与查阅文献相结合的方法,首先整理收集得到太平洲捷水道的基本情况,对太平洲捷水道现状做出整体评价。结合上述收集到的资料数据,对河床与浅滩进行演变分析,包含定性分析与定量分析,用BP神经网络预测方法预测了太平洲捷水道航宽演变趋势。采用指数平滑、一元回归、弹性系数等组合预测模型对水运量进行了预测,论证了航道通航标准,选取船型及营运组织方案,为整治工程方案设计提供依据。在演变分析基础上,提出了具体整治原则,进行了整治工程平面布置,计算确定了航道整治水位与整治线宽度;提出了两种具有可行性的整治方案,方案一采用护滩带和鱼骨型护滩带,以防止洲滩冲刷后退;方案二别采用了梳齿型护滩带和分流鱼咀,以促进滩体淤积。进一步地,对整治建筑物结构、护岸工程、疏浚工程进行设计。更多还原

【Abstract】 Taipingzhoujie channel in the lower reaches of the Yangtze River is studied in this paper,and then the corresponding channel remediation program is obtained.First,the basic information of the Taipingzhoujie channel is collected and summarized by the combination of field investigation and literature review,and the current situation of the Taipingzhoujie channel is evaluated.Second,the evolution of riverbed and shoal is analyzed by qualitative and quantitative analysis based on the collected data.And the BP neural network prediction method is adopted to predict the channel width and characterize the changes.Furthermore,the water transport volume is predicted by combining forecasting models such as exponential smoothing,one-dimensional regression,elasticity coefficient,etc.The channel navigation standard is demonstrated,and the ship type and operation organization scheme are selected to provide the basis for the design of the channel remediation project.Based on the analysis of evolution of the Taipingzhoujie channel,the specific remediation principles are put forward and the layout of the remediation project is carried out,and the water level of the channel regulation and the width of the rectification line are calculated.Two feasible remediation plans were put forward.The plan No.1 used beach belts and fish bones.Type beach belt to prevent the continent beach from scouring and receding;scheme 2 does not use the comb-type beach belt and the diverting fish nozzle to promote the accumulation of beach body.Furthermore,it is designed to rectify the structure of buildings,revetment works and dredging projects.更多还原
