Abstract

After the 1995 Great Hanshin Earthquake, ground fissures were found to have radiated from the footing of a bridge pier. Simple experimental and numerical studies were carried out to investigate the cause of these fissures. This paper clarified that the ground fissures appeared not as a result of the force due to the lateral spreading of the liquefied soil acting to the back of the footing of the bridge pier, but due to the movement of the ground behind the riverbank toward the river caused by the collapse of the riverbank.

The Cause of Ground Fissures Radiating From the Footing of a Bridge Pie Generated by the 1995 Great Hanshin Earthquake

San Diego, California

After the 1995 Great Hanshin Earthquake, ground fissures were found to have radiated from the footing of a bridge pier. Simple experimental and numerical studies were carried out to investigate the cause of these fissures. This paper clarified that the ground fissures appeared not as a result of the force due to the lateral spreading of the liquefied soil acting to the back of the footing of the bridge pier, but due to the movement of the ground behind the riverbank toward the river caused by the collapse of the riverbank.
