The design feature of Yichang vessel diesel engine plant self-used heavy cargo wharf is to transform part of the bridge technique to the gravity wharf design. One feature is to solve the strength and deflection problems caused by the over load on the suspension beam. The main beam adopts the large-span bridge design concept, choose the self-anchored cable-stayed cantilever beam design plan, reduce the self-weight of the steel box beam, and also reduce the construction difficulty. The other feature is that two main piers in the river adopt the large-span bridge pier design concept, adopt the large-diameter bored cast in-situ pile group foundation to help the main pier bear the torsion and ship breasting force transmitted from the main beam.The design of this wharf may serve as a reference for the relevant project design in combining the bridge technology.
