Outline of Final Research Achievements

In order to conserve and utilize existing stone bridge while maintaining it, the research on the following five items was carried out and research results were got. 1) The repair and reinforcement methods using stainless steel rod etc. were developed against the damage of the stone gap and crack existing in the stone bridge and confirmed by experiment. 2) Aiming at high strength of stone material high column, we developed high column which reinforced reinforcement and adhesion by epoxy resin were combined in stone, and confirmed the effect. 3) Development of a stone bridge type resistant to flooding was investigated by using model experiments. 4) The mechanism of the wall stone collapse due to the earthquake examined the relation between the wall stone and the filling material by the stone bridge miniature model experiment and confirmed the effect of the filling material. 5) The development and proposal of the design method of stone arch bridge were conducted.
