两种护岸新材料的应用技术试验研究

Experimental study on the application of two kinds of new materials to bank protection

通过对铰链混凝土沉排与模袋混凝土两种护岸新材料应用技术的试验,结合长江中下游河道护岸区及附近的水流泥沙运动、护岸材料及防护体的特性,分析研究了其护岸工程的效果、破坏机理及适用条件。研究表明,柔性的铰链混凝土沉排基本能适应河床变形,扩岸效果明显好于不易变形的硬性模袋混凝土,并提出了两种材料护岸工程的优化改进措施,可供护岸工程设计参考。

According to the experiment on application of two kinds of new bank protection materials（ hinged concrete slab mattress and mold- concrete） and the characteristics of flow movement and sediment transport in middle and lower Yangtze River, this paper analyses the effect of the two new materials on the bank protection, the the damage mechanism and applicable conditions. The results show that the flexible hinged concrete slab mattress can easily adapt to the deformation of riverbed and its protection effect concrete. In addition, the optimization and improvement measures on is obviously better than the mold- bank protection works of the two kinds of materials are suggested. This may be a reference for the design of bank protection works.
