Damage Investigation and Structural Analysis of Piled Berthing Structures During 1995 Hyogoken-Namhu Earthquake

摘要

A certain extent of damage was caused in port structures due to 1995 Hyogoken-Nambu (Kobe) Earthquake. After this event, discussion has been actively made if the design code on piled berthing structure is revised. This paper presents the results of damage investigation on an open-piled marginal wharf and makes clear the mechanism of the process of damage by comparing the results of numerical analyses and shake table tests with the observed results. It was made clear that the wharf has highly seismic endurance unless retaining walls move towards the wharf. Moreover, it was confirmed that liquefaction of the ground may cause buckling of piles due to large movement of wharf.
