黄河下游少抢险坝垛结构探讨

Research on Structures of the Less-emergency Dam along the Lower Reaches of the Yellow River

柳石结构丁坝一般需要抢险才能稳定，多数少抢险坝垛结构也不同程度地存在缺陷，本文认为长管袋褥垫沉排坝是丁坝较为理想的结构型式。

The willow-stone groyne is generally stabilized by many emergences, most structures of the less-emergency dams have shortcomings in varying degrees. The long-pipe cushion matress dam proved to be a more ideal smictural form.
