| Research Abstract |
Many important infrastructures in Japan are located on the soft ground, such as Alluvial plain and coastal artificial reclaimed ground where extensive seismic damages are expected to occur. This research tries to reevaluate the seismic resistance of coastal areas in the event of large-scale serial ocean trench earthquakes with a consideration of ground reinforcement technologies. Existing damage prediction methods focus primarily on seismic stability assessment during an earthquake and are inadequate to forecast ongoing long-term ground settlement which inevitably occurs after an earthquake. To use a new numerical technology to evaluate the seismic and post-seismic resistance capabilities of natural and artificial soils in systems, in parallel with the existing methods, it will be responsible not only for a accuracy enhancement but also for preventing oversight of the serious seismic damages.
