The data of environment,hydrologic condition,durability design and load design are surveyed and collected.The durability monitoring sensors are embedded in the construction period to monitor the durability degradation from the beginning of the construction period to obtain key durability parameters of the project.The exposure test stations are built to carry out the exposure test investigation with the same raw materials and mix proportion to the project.While at the same time,the durability of the concrete also with the same raw materials and mix proportion to the project is carried on in laboratory.Therefore,the differences of the durability degradation among the projects,exposure tests and laboratory studies could be investigated and the relativity would be built.It could guide the design and construction of marine concrete structures.
