河流、渠道在农田水利工程中占有十分重要的地位,加强河流、渠道的管理,保护好河、渠的岸坡,确保工程完好,对引水、排水和航运的畅通具有重大的经济意义。如何因地制宜地选择技术经济都适应的护岸形式是需要经过长期实践和摸索的,根据我县不完全的统计,解放后已建成斜坡式的干砌护岸16.46公里,重力式干砌石直立墙护岸19.7公里,由于各种原因出现不同程度破损的分别达66%和50%左右。而近十年来我们在总结过去经验教训的基础上,摸索采用了近似直立的组合式和复式与肋形座的干砌护岸,技术经济效果有了明显的提高,
Rivers and channels occupy a very important position in farmland water conservancy projects. It is of great economic significance to strengthen the management of rivers and channels, and to protect the banks of river and canal so as to ensure the integrity of the project and the smooth flow of water, drainage and shipping.

Km, due to various reasons, different degrees of damage were 66% and 50% respectively. In the past ten years, on the basis of summing up the past experiences and lessons, we explored the use of a combination of approximate upright and duplex and rib seat dry revetment, technical and economic effects have been significantly improved,
