Abstract: The construction of marine structures is very common in engineering. A complete coastal wharf consists of pile foundation, pile cap and superstructure. This dissertation is mainly about a project of pile cap. In previous projects, it was a common practice to use a prefabricated system (pile cap) as a template and then construct a concrete stencil on the bottom or side formwork. Considering the problems of typhoon, corrosion and steel mold stability in the marine environment, how to shorten the construction period and build a more optimized and stable structure is a big challenge. Accordingly, this thesis is based on a marine structure project with such a trouble. In this report, we propose a practical approach, which combines two materials UHPC (reinforced ultra-high performance concrete) and FRP (fiber reinforced polymer) to produce a permanent formwork, after that workers will pour concrete in lifts to make it a new pile cap system. In this study we conduct a feasibility study on formwork made of UHPC and FRP, in the next step we deal with a problem of how to design structure of this pile cap formwork under two limit states using finite element analysis method. Namely, we design the pressure model of the pile cap and platform upon ABAQUS in the marine environment. Compared with the existing methods, the FRP-reinforced ultra-high performance concrete (UHPC) permanent formwork can improve safety under the same bearing capacity. Considering the advantages of shortened construction period and enhanced corrosion resistance of the pile cap system, the method is feasible in marine structure construction. We hope this approach can lead us to apply these two civil engineering materials to engineering practice and provide examples of research materials.
