Abstract
<p>Recently, 3-dimensional measurement can be conducted easily by using the UAV as like drones. Although the precise geological survey has been possible by the new technology, the 2-dimensional dynamic finite element analysis is still common in the design problems. The 3-dimensional finite element modeling technic by extending the 3-dimensional measurement results to the subsurface area, has been developed by the authors. In this research, the 3-dimensional measurement is conducted by using a drone, from the taken pictures of an earth-fill dam, 3-dimensional point group data are generated, and 3-dimensional finite element model of the earth-fill dam is completed from the point group data. Based on the model, 3-dimensional seismic response analysis can be conducted. Consequently, from the analytical results, the structural weak points of the earth-fill dam have been clarified, and in the comparison between 2-dimensional and 3-dimensional analyses, the possibility of underestimation for the seismic behavior by the 2-dimensional analysis have been suggested.</p>
