摘　　要：对铅丝笼丁坝的应用概况、优点、设计要点及研究方向进行了分析,结果表明：铅丝笼丁坝具有造价低、施工速度快、自适应性强、选材容易及具备透水性等优点;建议铅丝笼长2-5m、宽1-2m、高0.5-1 m、孔眼尺寸为15 cm×15cm,坝头宜呈圆滑曲线状;铅丝笼丁坝宜修建为下挑式,挑角为45°-90°;丁坝间距与所处位置有关,一般凹岸较密;下一步的研究方向包括丁坝附近的水流结构、缓流落淤效果及水毁机理等。The advantages,design parameters,future research directions and some problems exist in the overall design of gabion groin for bank revetment are discussed.The results show that the gabion groin have low cost,fast construction,self-adaptable,permeability and other advantages;The author made a general recommendation of the size of gabion： length 2-5 m,width 1-2 m,0.5-1 m high,hole size 15 cm × 15 cm,smooth curve-like on the head;meanwhile,groin for bank revetment should be constructed for some acute angle,optimal design is 45°-90°;groin spacing depends on the locations of project,generally,more dense on the concave bank.Future research directions are the flow structure near the groin,the effects of deposition falling with tranquil flow and the mechanism of water damage,are discussed.
