Open publisher page 0 citations

Abstract

Based on the statistics of the risk spot and risk section, including ancient flood mouth, piping, seepage, fissure, dike body incompleteness, breach, and flood running alongside dike, it is found that the seepage deformation is more than 46% of all the risk cases. This also demonstrates that the seepage deformation should be given first priorities. By the end of 2002, 113 locations of risk listed has been basically removed through dyke strengthening: prop built either in front of the dike, or behind of the dike, vertical cutoff wall and cone grouting. There is a tendency of risk decline of the Yellow River dike year by year. The construction of standardization dike will enhance the safety of the Yellow River dike.
