Outline of Final Research Achievements |
A finite element analysis, in which crack growth was mainly considered, was conducted in order to solve recent problems related to irrigation dams. As a result, the mechanisms of direct shear were interpreted especially through an analysis of model tests. Furthermore, a seismic analysis was also carried out for the dam bodies from which fundamental knowledge was obtained. At the same time, some experimental analyses were also carried out. Fundamental knowledge of the strength of the core materials of dams, discontinuous rock masses, and the joints of concrete were also obtained from the analyses.
