A SIMPLE EVALUATION METHOD FOR EARTHQUAKE DAMAGE TO THE QUAY WALLS

摘要

In Japan, a lot of reclaimed lands had been constructed for port and industry facilities since the head of the 20th century. A reclaimed land is generally composed of both the quay walls and the backyard ground. A key of the seismic safety of reclaimed lands is sustainability of the quay walls. A simple evaluation method for earthquake damage to the quay walls has been constructed empirically based on actual earthquake damage by such the past earthquakes as 1995 Hyogo-ken Nanbu and other moderate magnitude earthquakes. This method is limited to be applied in order to pick up the weak quay walls with less seismic performance.
