Taking the design of Jiuzhou Rive Bridge for an example, its structural characters and its design calculation method are briefly introduced. And for decreasing the probability of the piles which cross the water-eroded cave, the twin shaft pier and the prestressed coping are adopted for the substructure and foundation of the bridge in the whole width range of it.
