Abstract

Xie, Y.P. and Li, X.H., 2020. Influence of the coupling effect of ocean currents and waves on the durability of pier structure of cross-sea bridges. In: Al-Tarawneh, O. and Megahed, A. (eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 87–90. Coconut Creek (Florida), ISSN 0749-0208.

In the marine environment, under the action of ocean currents and waves, the piers of cross-sea bridges face a series of durability problems such as salt erosion and salt freeze-thaw cycles. The durability of the pier structure directly affects the service life of cross-sea bridges, so the research and test on the durability are of important significance for the design of cross-sea bridges. Based on the coupling effect of ocean currents and waves in the marine environment, this paper explores its influence on the durability of the pier structure of cross-sea bridges. The research results show that the durability analysis includes environmental index calculation, durability index calculation and durability evaluation. The damage of the bridge pier concrete structure is related to the material composition and the deterioration of the macro performance of the microstructure under the action of special environment. The pier concrete of the target cross-sea bridge measured in the laboratory has a salt-freeze resistance greater than F300. This paper provides an important theoretical basis for the research on the safety of marine concrete structures.
