丁坝坝头在水流冲刷下的有效防护

Effective protection of the spur dike head under current scour

针对丁坝坝头处冲刷的问题,依托孟加拉国贾木纳河右岸丁坝防护项目,研究探讨了丁坝坝头处的冲刷机理和主要影响因素。基于河流动力学基础理论,提出了丁坝坝头处的防护改进措施。采用原型观测方法,进行坝头处的有效防护研究,提出的方法防护效果良好。

For the problem of scour on the spur dike head,the scouing mechanism and the main influencing factors are discussed in this paper,based on the protection project of the spur dike in right bank of Jumuna River in Bangladesh.Based on the basic theory of river dynamics, this paper puts forward the measures to improve the protection of the spur dike head.Using the method of prototype observation,the effective protection research of the spur dike head is carried out,and the proposed method is effective.
