Effects of Scouring on Performance of Caisson Foundation

Caisson foundation is a common type of foundation used for cross-river bridges in Taiwan. In this paper, failure envelope with respect to scouring depth, river flow velocity and water level effect is used to study how decisions are made on the closing of bridges during severe storm or typhoon. Two caisson case studies are also presented to check the applicability of the used method. The analysis results show that among the three factors considered in the failure envelope, variation of scouring depth and river flow velocity have higher influence on caisson foundation stability than the water level change.
