On Several Problems of River Training

治导线规划是河道整治规划中的一个主要内容。一般平原河流应考虑中水河床和洪水河床两种情况 ,山区河道只考虑洪水河床。河道整治宽度确定之后 ,治导线基准点的确定是河道两岸十分关心的问题 ,应遵循一些原则。在治导线连接上 。

In this paper,the following are included:〔1〕the basic principle of the river training,which is summarized as“through overall planning to do comprehensive training,guiding the training in the light of river's situation and giving priority to the training of the key reaches”.〔2〕determining the width of river training,for which both the median water riverbed and flood riverbed should generally be considered for the plain river while only the flood riverbed may be considered for mountain river.The methods of determining the width of river training being given.〔3〕determining of the base point(or line)of the river training line is one of the main content in the river training works,which,however,depends on its base point(or line)after the width of river training has been decided.Some principles and items to which attention should be paid for fixing the base points(or line)of training line are illustrated in detail according to the river training practice of the author.Finally,the connection methods for the river training line are introduced for median water riverbed and flood riverbed respectively.
