Abstract
Because the influence of displacement induced by an active fault, especially an active surface fault on highway bridges has not been clarified, the countermeasures against the displacement by an active surface fault have not been applied in earnest in Japan. However, the investigation results on active faults have been open to the public in recent years in Japan. The construction projects will be not a little related to active faults in the near future. Therefore, it is very important to establish the practical procedures on countermeasures for highway bridges against the displacement by active faults.
In this study, the practical procedures are proposed based on the actual plan for a newly-constructed highway bridge at Beppu City in Oita Prefecture which is the first project considering the effects of an active fault in real earnest in Japan.
