Both the first and second phases of the Dongjiakou crude oil terminal project of Qingdao Port have been completed，with a 300，000 DWT berth and a 100，000 DWT berth as well as corresponding approach bridges and supporting facilities.According to the structural characteristics of different marine structures and the favorable conditions of moderate bedrock depth in the project area，gravity structure and high pile pier structure are adopted for the wharf and approach bridge respectively. In view of the problems of complex wave and current conditions in the open sea and poor construction support conditions，a scheme combining the open space structure and prefabricated components with the hanging basket construction of the approach bridge is adopted. The expected effect is achieved. Starting from the marine structure scheme of the two projects，this paper comprehensively analyzes and summarizes the characteristics and innovation of the two projects，to provide experience reference for the design of similar projects.
