Laboratory Test
Laboratory tests with soil sample are used to understand the mechanical properties of soil. The major research subjects are the followings.
Monotonic and cyclic triaxial compression test
Monotonic and cyclic hollow cylindrical torsional shear test for sand and clay
Centrifuge Model Test
Geotechnical centrifuge tests are used for the physical modeling of ground and structures. The major research subjects are the followings.
Deformation and failure of embankments such as river levee, landslide dam during seepage and overtopping
Deformation of structures due to liquefaction
Development of instruments for site monitoring
Geotechnical Earthquake Engineering
Cyclic hydro-mechanical properties of soil and seismic behaviors of ground and structures during an earthquake are studied to mitigate seismic geotechnical hazards. The major research subjects are the followings.
Cyclic deformation of saturated and unsaturated soil
Liquefaction of sandy soil
Liquefaction-induced settlement and lateral flow of ground
Seismic behavior of foundation in a liquefied ground
Failure of soil structures such as fill slope and embankment
