Abstrait:

This paper presents a case study of underpass situated on Säterinpuistontie Street as part of the ESKA railway widening project in Finland which facilitates a cycleway, road, and tram tracks passing under the railway. Due to the proximity of the water table to the ground level in this area, specific design considerations are necessary to prevent structure uplift. The primary objective of the case study is to conduct a comprehensive comparison of the material, cost and carbon emissions between two distinct design approaches for watertight U-shaped reinforced concrete trough structures which involves a gravity structural system using high-density concrete and normal- density concrete with structure anchored to the base rock using steel anchors. The study aims to emphasize design methodology, variations in structural analysis methods employed by these approaches and provides a comprehensive understanding of the environmental and economic implications.
