Outline of Final Research Achievements

Characteristics of Nankai Trough Earthquake are a long predominant period, a long duration, attack of tsunami after the strong shaking and a extensive damage area. In this study, we make clear an aseismic safety level of infrastructure, structural and functional capacity of infrastructures for the social requirement and the countermeasures for preventing earthquake damage. We assessed an adequate input ground motion for the design of structures, and evaluated the earthquake and tsunami prevention strategies and countermeasures especially for lifeline systems such as railway, roadway, water, gas, electricity and various pipelines. In order to realize these issues and extend the applicability, we conducted numerical simulations by using such advanced simulation methods as FEM, DEM and SPH. Centrifuge experiments were also conducted to verify such computer simulation. The results obtained would be useful resources for soft and hard measures of mitigating earthquake and tsunami disasters.
