【摘要】 沅水尾闾段水网纵横 ,航道条件错综复杂 ,洪道中发育有复杂分汊、弯曲等河型 ;水文条件不仅受沅水干流的影响 ,且受洞庭湖其它水系及长江的来水来沙影响。其特殊的地质条件和周边环境 ,加上洪水对两岸的威胁 ,河段亟待进行综合治理。在沅水尾闾段水文特点分析的基础上 ,提出了航道整治措施 ,其航道整治方法具有一定的典型性和代表性 ;对入湖尾闾段航道整治一般特点进行了分析 ,在航道选线和处理航道整治与洪道整治的关系方面 ,对类似工程具有借鉴意义更多还原

【Abstract】 The tail of the Yuanshui River is a crisscross network of waterways. There are many complicated braiding and bending channels in the flood ways. The hydrological conditions are affected not only by the main stream of the Yuanshui River, but also by others water systems and the conditions of incoming water and sediment from the Changjiang River. It is urgent to practise all round regulation because of its special geologic conditions, boundary conditions and the danger of flood to the riverbanks. Based on analysis of the hydrological characters of the tail of the Yuanshui River and the general feature of channel regulation in the river section entering into lake, the measures of channel regulation are put forward. It is representative and typical of channel regulation and can be used to similar project for reference.更多还原
