Abstract

The Kobe Earthquake in Japan caused shallow sliding on the upstream slope below the water level of the Kitayama Dam. This paper briefly stated the results of post-earthquake surveys and tests of this earth dam. The FE model of the dam was prepared based on the detailed results of in-situ tests and laboratory material tests. The numerical analysis was performed by the effective stress analysis to simulate the performance of the dam during the Kobe Earthquake. The analysis resulted in that large residual deformation and shear strain occurred at the shallow area of the upstream slope below the water level. The analysis was able to simulate the behavior and damage pattern of the dam, that is sliding deformation, during the Kobe Earthquake.

Numerical Simulation of Sliding of an Earth Dam During the 1995 Kobe Earthquake

San Diego, California

The Kobe Earthquake in Japan caused shallow sliding on the upstream slope below the water level of the Kitayama Dam. This paper briefly stated the results of post-earthquake surveys and tests of this earth dam. The FE model of the dam was prepared based on the detailed results of in-situ tests and laboratory material tests. The numerical analysis was performed by the effective stress analysis to simulate the performance of the dam during the Kobe Earthquake. The analysis resulted in that large residual deformation and shear strain occurred at the shallow area of the upstream slope below the water level. The analysis was able to simulate the behavior and damage pattern of the dam, that is sliding deformation, during the Kobe Earthquake.
