5. Research Experience:

A: Development of a new research field of landslide dynamics to protect human lives.

Landslide dynamics is to assess the initiation and post-failure motion of landslides. A rapid disastrous landslide was triggered by the 1995 Kobe earthquake without rains and without a torrent. It is because of the sliding surface liquefaction where a shear zone is liquefied because of grain crushing and volume reduction during shaking and post-failure shearing. It is a key phenomenon to trigger rapid and long-runout landslides. It was presented in major papers No.6, 7. 11.

To reproduce the sliding surface liquefaction and measure porewater pressure in the shear zone during the initiation and the motion of landslides within the apparatus, a new dynamic-loading undrained ring shear apparatus was developed and it was improved in undrained capacity. It was presented in major papers No.13,14, 18,19.

A new computer simulation model for the initiation and the motion of landslides using the measured parameters of pore pressure generation and shear resistance mobilized in the shear zone was developed and it was improved. It was presented in major papers No.4 (initial type) and No. 21 (improved type: Landslide simulation model for rapid landslides: LS-RAPID).  The model was expanded to simulate landslide-induced tsunami by combining landslide simulation model and tsunami simulation model. It was presented in major papers No.26. The dynamic-loading undrained ring shear apparatus and the computer simulation model LS-RAPID was widely applied for various landslide cases. It was reported in major papers No.15,17, 22, 23.

Landslide dynamics for landside hazard assessment has reached a level of the practical use. It was presented in No. 24 in the World Landslide Forum 3 and published in Landslide Dynamics: ISDR-ICL landslide Interactive Teaching Tools.

B: Research for landslide hazard assessment at cultural heritage sites

Cultural heritage sites are usually stable areas for some hundred years or more. However, they can be affected by landslides because of long weathering, neotectonic process, river erosion, ground water pumping and other human activities. A series of long-span extensometers and other monitoring equipment together with drilling and tunneling presented the landslide risk at the precursor stage of deformation. This research was applied to the Royal Palace in Tang Dynasty (A.D. 618-907) in Xian, China, and also Inca’s World Heritage “Machu Picchu”. It was presented in Major papers No.8, 9, 12, 16, 20, and both were presented in No.25 as a keynote lecture for IAEG Congress.
