漫水丁坝和丁坝群防护的试验研究

Experimental Study on Submerged Spur dikes and Protecting Scour

根据水工模型试验研究和工程现场考察，对漫水丁坝附近的水流结构，河床变形的特点进行了分析和研究；以不漫水丁坝为基础，提出了漫水丁坝冲刷深度的计算方法；从总结工程实践经验出发，提出了关于坝型、不同地区、不同河段等条件下修建漫水丁坝及丁坝群方面的建议。

Based on model test and the scene investigation, the flow structure around submerged spur dikes and evolution characteristic of river bed are researched .One calculation method on scour depth of submerged spur dikes is raised.Some rational proposals are put forward for building the submerged spur dikes in different conditions.
