Abstract: The use of high-durability and high-strength FRP bar reinforced concrete rather than the reinforcing steel bar to conduct marine concrete breast wall structure construction project can drastically lower the later maintenance cost of marine infrastructure construction projects. Based on the plane cross-section assumption in the engineering mechanics, a design requirements formula for the fracture and the reinforcing bars is established; in reference to a large-scale port construction project, the pre-bending and linear FRP steel bars are selected to conduct the building process analysis. The results of wavelength monitoring show that the FRP concrete breast wall structure is characteristic of deformation stability and the projects thus constructed is of excellent quality.
