Scour is one of the major causes for bridge failure. To prevent this type of failure, it is necessary to detect the scour of abutment foundation. As a dependable method to measure scour, the underwater detection technology has been used to determine the scour degree of abutment foundation of the Zishui bridge of Xiangqian railway in China, and the transverse and vertical displacements of the bridge piers were analyzed resulted from different scour degrees of the abutment foundation. The results showed that the maximum transverse and vertical displacement of the bridge piers depended mainly on the ultimate scoured area of foundation base.
