Outline of Final Research Achievements

Explication of local deterioration mechanism, development of diagnosis method and proposal for construction method about frost damage of an open channel and water bridge in cold regions were studied by this research. Visual observation technique of a side wall, technique for the degradation grade by electromagnetic wave rader and ultrasonic method were cleared by a study in 2012. Diagnosis methods by resonance vibration, evaluation technique of the degradation by low-pressure silane injection were cleared by a study in 2013. Fundamental planning of the method for rehabilitation of channel in cold regions was performed by the study which was done based on the generation mechanism of frost damage made clear by the former study in 2014.
