| Outline of Final Research Achievements |
A large number of the steel sheet pile canal has been widely used in Japan. In recent years, the relationship between the durability and the corrosion of the steel sheet pile has been discussed as a technical problem. In this study, development of conservation method for corroded steel sheet pile in canal structure was performed, applying steel sheet pile - concrete composite. The experiments were conducted as test constructions and a bending test by the model samples. In these experiments, the bending properties of composite are evaluated based on displacement measurement and AE. Thus, the mechanical properties of composite could be evaluated by comparing a moment with a maximum displacement. The AE generation behavior is correlated with fracture process in load-displacement characteristics. The experimental result, the covering effect of concrete is quantitatively evaluated.
