河道截流

从河道截流的发展趋势来看，高水头截流已成为一种趋势。

Higher water head closure has become a trend with the development of river way closure .

河道截流工程的进展与研究

Development of River Channel Closure Works

河道截流在水利水电工程建设中占有十分重要的地位，其安全性、经济性和可实施性一向受到高度重视。

Closure plays a key role in the construction of water resources and hydropower projects , People usually pay more attention to its security , economy and application .

围绕截流龙口处的水力参数获得以便为截堤堤头坍塌数学模型计算提供必要的已知条件，本文建立了河道截流水流数学模型，并给出其求解算法及工程计算实例。

In order to attain hydraulic parameters in closure gap and so that present the needed condition for mathematical model solution of dyke nose slump , a mathematical model of current in river channel is established and its solution and engineering computation example are given .

它的成败，直接影响着工程的工期和造价，特别是在大流量、高落差、软基河槽、全年需要通航的河道上截流，则更是一项艰巨而繁重的任务。

Its Success or failure , influence the time limit for the project and fabrication cost directly . Especially closure in the large flow , high fall head , soft base channel , navigation during the whole year , is an arduous and strenuous task even more .

叙述了国内外河道高落差截流工程的进展情况。

Development of high drop river closure work in China and abroad is elaborated in this paper .

如何使通航河道在水电站截流至船闸正式通航期间维持正常的航运，其做法不一。

There are differents ways to maintain normal navigation in navigable channel during channel enclosure for building hydropower plant .
