permeable dike

While serve for beaching of bank, permeable spur dike could elaborate meantime merit sever of discontinuity revetment slacken littoral current velocity, brought accumulation of sediment, touch the object to preserve bank.

当用作护岸工程时，丁坝可以发挥其间断性护岸的优点，减缓近岸流速，促使泥沙淤积，达到保护堤岸的目的。

To improve the river reconstruction technique, it is necessary to investigate mechanism and effect of flow control and aggradation for permeable pile dike.

为了探索透水桩坝在黄河治理中的应用前景和应用技术，进一步研究和探讨该工程的透水落淤机理和导流效果，为防洪治河提供理论依据。

More than that, at thoroughfare, bridge crossing engineering, permeable spur dike useful for fence bed, led mainstream through the medium of bridge opening.

不仅如此，在道路、桥渡工程中，丁坝可用于防护路基，引导主流通过桥孔。

Permeable pile dike is an important method for stream control in river restoration or construction, and is of some marked advantages including deep groundwork, large strength, simple construction, little emergency, easy maintenance, effective control on the flow trend and increasing the sedimentation.

透水桩坝是河道整治工程中的一种，由于其根基深，强度大，施工程序简便，具有少抢险，易护理，同时具有控导河势和在滩地缓流落淤等功效。

Research on Effects of Deposition Falling with Tranquil Flow of Permeable Pile Dike for Bank Protection and Scouring Process around the Pile Position
