Abstract

Ports are often regional economic centers and important components of regional and local transportation lifeline systems. Because of these reasons, the downtime of the ports due to natural disaster such as an earthquake results in severe economic loss. Gravity quay walls are the most common type of construction for docks because of their durability, ease of construction and capacity to reach deep seabed levels. Past earthquakes demonstrated that the seismic behavior of port structures such as quay walls was significantly governed by the properties of soils. The 1995 Hyogoken- Nanbu (Kobe) Earthquake brought great damage to structures in the Port of Kobe, which is one of the primary ports in Japan. In the present work, caisson type quay wall, damaged by 1995 Hyogoken- Nanbu earthquake, is first numerically analyzed and then seismic behavior of quay wall is investigated. The results are also compared with the observed data consisting seaward displacement, tilting and settlement. The results of the numerical analyze shows good agreement between the numerical simulations and observed data.

Evaluation of Deformation Behavior of Quay Walls Under Earthquake Loading

San Diego, California

Ports are often regional economic centers and important components of regional and local transportation lifeline systems. Because of these reasons, the downtime of the ports due to natural disaster such as an earthquake results in severe economic loss. Gravity quay walls are the most common type of construction for docks because of their durability, ease of construction and capacity to reach deep seabed levels. Past earthquakes demonstrated that the seismic behavior of port structures such as quay walls was significantly governed by the properties of soils. The 1995 Hyogoken- Nanbu (Kobe) Earthquake brought great damage to structures in the Port of Kobe, which is one of the primary ports in Japan. In the present work, caisson type quay wall, damaged by 1995 Hyogoken- Nanbu earthquake, is first numerically analyzed and then seismic behavior of quay wall is investigated. The results are also compared with the observed data consisting seaward displacement, tilting and settlement. The results of the numerical analyze shows good agreement between the numerical simulations and observed data.
