Abstract

The length of Yellow River downstream course is approximately 800 km with the dike length of 1 371 km. The hidden trouble concealed under the dike¡ªseepage stability of dike foundation old gate is geological problem of dike foundation and major issue of embankment management, plan, reinforcement, and reconnaissance design of Yellow River downstream. Therefore, it is necessary to implement widespread analysis and research on historical breach old gate and data of dike seepage deformation of previous big floods.
