| Using a case history of earthquake damaged sluice pipe, an analysis with newly developed performance based design methodology on the sluice pipe reinforced with RC piles was carried out so as to examine the validity of the newly developed procedure. In this paper, damage mechanisms of the sluice pipe due to the 2003 Tokachi-oki earthquake, which was named as Ohtsu city sluice, was briefly summarized at the beginning. After brief descriptions on the newly developed procedure, where the effects of ground deformations associated with liquefaction caused by large earthquake were taken into account, result of analysis was com-pared with the observed extents of the damage. It was found from the analysis that the evaluated extents of the damages were corresponded well with the observed ones in the field surveys. |
