| Outline of Final Research Achievements |
To promote earthquake countermeasures for spatially complex networks of systems such as lifeline structures, it is necessary to countermeasure against surface fault displacement to avoid affecting the function of the entire system. This study aims to develop a new mechanical theory of fault displacement caused by slip partitioning and bifurcation faults and to predict them with high accuracy. We developed a numerical analysis method that can analyze branching faults. Then, several specific cases (the 2016 Kumamoto earthquake and the 1992 Landers earthquake) are discussed.
