Study on estimation of the typical hybrid levee degradation of osmotic resistance caused by piping¡¥

Satoru OHTSUKA

In recent years, occurring due to local severe rain and typhoon by heavy rain result from an increase in riverbank failure. A bank adding an external force sheet pile and have arise from space between. Water way is formed by action of water flow into a space. Result from elevation of permeability flow out ground material and be triggered by the burst of the ground.
In this study, we aimed to investigate osmosis resistance empirically. Result of someone's investigation osmosis resistance empirically, When a sheet pile is installed, there is an effect which controls osmosis. Water way is rised by the presence of infiltration performance.
Fluctuation of water level is stable in property. So that means sheet pile not pulling that weight. The bigger Water way, The water level get higher, become widespread collapse prone.
