摘  要：
针对丁坝坝面及背水坡水毁问题,采用物理模拟方法,进行正态水槽概化模型试验研究。通过试验,分析丁坝坝面及背水坡的水毁过程,找到破坏的关键点。在此基础上,分析丁坝坝面及背水坡水毁机理,根据相应部位水流特点及破坏形式设计出混凝土浆砌条石护面和混凝土块铰链排护面2种整治防护结构,并对2种结构进行比选。试验结果表明:丁坝坝面及背水坡水毁的主要动力是高速翻坝水流,破坏程度与丁坝前后的跌水高度有关,混凝土块铰链排护面结构具有较好的防护性能。

摘  要：
To solve the waterlogging problem of spur dike dam surface and back water slope,The physical simulation method was used to do the normal sink generalized model test research.Through experiment and the analysis of waterlogging process of spur dike dam surface and the back water slope,the key point of damage was found.On this basis,we analyzed the waterlogging mechanism of spur dike dam surface and back water slope,and designed two kinds of protection structures according to the slurry flow characteristics and damage forms of corresponding parts:concrete grouted block stones protective structure and concrete hinge line surface protection structure.By comparing the two kinds of structures,the results showed that the waterlogging of spur dike dam surface and back water slope was mainly caused by high dam water flow and the damage is associated with the drop height of water before and after the spur dike.The protective structure of block hinge line demonstrated good protection performance.
