The design criteria of escape passages at dangerous goods wharfs are ambiguous in the prevailing specifications, and the locations of escape passages in existing projects are unreasonable and fail to ensure the safe and rapid escape of people in emergencies.Considering these problems, this study investigates the stress characteristics of the steel-reinforced concrete structure and its adaptability in offshore engineering structure design.As a result, it introduces a structure for water escape passages on the basis of the prefabricated steel-reinforced concrete structure and applies it in the design of the wharf structure.Furthermore, by summarizing the features of this structure, the paper also put forward countermeasures to tackle the major difficulties.The results show that the structure can remove the obstacles in the setting space and construction water level of water escape passages, featuring controllable quality, convenient installation, and assured safety and reliability.Hence, it is a supplement and alternative to the design of water escape passages at wharfs and is conducive to enriching the safety facilities of offshore wharfs.
