Abstract;To convert from a minimum material to minimum manpower, the research of the structure which replaces a past beam slab type viaduct is actively done in the railway viaduct. Recently, it is necessary to increase a concrete quality and durability because the accident concerning the concrete of the tunnel and the viaduct occurred. Moreover, it is expected to become cheap in the life cycle cost though an initial construction cost of the self-compacting high strength and high durable concrete structure is comparatively expensive. Then, to establish the construction system utilizing the self-compacting high strength and high durable concrete, authors paid attention to the term of works shortening and the labor saving, and did the cost analysis of the railway viaduct. As a result, the structural type utilizing the self-compacting high strength and high durable concrete almost becomes equal with a past structure in an initial construction cost. Moreover, the structural type confirmed becoming in the life cycle cost the advantage by the high durability of the self-compacting high strength and high durable concrete. (author abst.)
