Abstract
For the plan and design of a bridge crossing an active fault, the design including alignment change or consideration of the fault displacement can be possible by knowing the fault location with a certain accuracy by the soil investigation. This paper presents ① detection of the active fault zone, ② evaluation method for the fault activity based on ground conditions, ③ evaluation method for the excavation stability behind the bridge pier, and shows the technical knowledges obtained by a series of soil investigations for the restoration of Kumamoto Earthquake disaster.
