Hydro-mechanical experiments on suffusion under long-term large hydraulic heads

The results indicate that: The signs of suffusion failure in the short-term experiments are the sudden decrease in hydraulic gradient and the sharp increase in eroded mass

Scholarcy highlights

  • The long-term large hydraulic head in flood season is the main cause of suffusion failure or dam break, while the suffusion failure mechanism in this case has not been specially studied
  • The results gained here provide a deeper understanding on the suffusion failure caused by the rapid increase in the high water level upstream the hydraulic earth structures in flood season
