Based on the physical environment of the life prediction model for marine concrete structures in China, taking the Visual C #. NET and the IMSL C # library as the platform, we developed the life prediction software for marine concrete applicable to China, the System for Durability Life Prediction Healthily of Harbor and Marine Concrete Structures v1.0. The mathematical model and data of the software come from the main results of the Western communications construction project of the Ministry of Transport, Durability Life Prediction and Health Diagnosis of Marine Concrete Structures. This system has a broad application prospect in the actual production. By this system, we can realize the durability design for the new construction, and prediction of the remaining service life for the old construction.
