Liquefaction of river levee |
Stability of river levees River levees in Japan sometimes breach due to infiltration of rain and river water, overflowing, and erosion. |
Desaturation by Air injection Development of innovative liquefaction counter measure technique enhancing liquefaction resistance of sand by desaturation |
Ground improvement by CaCO3 precipitation Mechanical properties of sand improved with calcium carbonate precipitated |
Combined load-displacement model for shallow foundations Macroscopic constitutive model for the entire soil-foundation system has been constructed, which is capable of predicting foundation behavior considering effects of horizontal inertia force of ground and cyclic loading |
Seismic stability of Masonry retaining walls A simple method to assess seismic stability of masonry walls retaining road embankment in mountainous area |
Seismic stability of tailing Dams |
Geotechnacal centrifuge technology Geotech group of Ehime University has developed its own centrifuge in 2007 and successfully operated. A mechanical shaker and 2D loading system has also been developed. Verification of generalised scaling law, LEAP project. |
