This study takes the first fully prefabricated high-pile wharf in China as the research object to compare the economy of the fully prefabricated high-pile wharf with that of the traditional high-pile wharf.Specifically, it analyzes the engineering cost composition of the fully prefabricated wharf platform by calculating the concrete consumption and the prefabrication rate of each part of the two wharf platforms.Then, it compares them in the direct construction cost, the financial cost of construction, and other aspects.The results show that the fully prefabricated wharf is more economical than the traditional one in the above-mentioned aspects, which can provide a basis for promoting fully prefabricated high-pile wharfs.
