黄河险工坝岸是抵御洪水、确保黄河安全的重要河工建筑物。坝岸从总体结构来看,可分根石部分和坝身两部分,其中根石是坝岸稳定的基础。根石传统结构是散抛石块裹护根石土胎,这样在水流冲刷下,一部分石块容易离开坝体,被冲刷揭走,这种现象称根石走失。根石走失使根石坡度变陡,严重时使根石发生坍塌,破坏坝岸基础,危及坝岸安全,因此,根石走失是引发坦石变 Yellow River dangerous work dam shore is to resist floods, to ensure the safety of the Yellow River important river structures. Dam bank from the overall structure point of view, can be divided into two parts of the root stone and dam body, of which the root stone is the foundation of the stability of the dam. The traditional structure of root stone is scattered rubble stone wrapped root stone, so that in the water erosion, part of the stones easily leave the dam, was washed away, this phenomenon that the root stone lost. The loss of root causes the steepness of the root steep gradient, serious rupture of the root stone, destroy the foundation of the dam and endanger the safety of the dam, therefore,
