地震被害分析のための3D-GISによる盛土・切土地盤の区分評価 Assessment for classification of ground between fill and cut using 3-D GIS for earthquake damage analysis 岩井, 哲 イワイ, サトシ 熊本, 道代 クマモト, ミチヨ Iwai, Satoshi Kumamoto, Michiyo 455 Geographic Information Systems the 2001 Geiyo earthquake wooden house damage fill ground cut ground application/pdf The damage to wooden houses caused by the 2001 Geiyo earthquake was surveyed at residential districts arround the western part of Hiroshima City; Koi-ue in Nishi-Ward，and Ajinadai in Hatukaichi City. Extensive damage of roof-tiles of wooden houses occurred on the fill ground more than the cut ground in an improved land. In this study，the assessment method is developed for classification of ground between fill and cut using 3-Dimensional Geographic Information Systems (3-D GIS) technique. TIN (Triangulated Irregular Network) and Overlay tools are employed against old and new 3-D geographical surfaces of residential districts in order to make classification of ground between fill and cut. Subsequently，the depth of fill or cut is calculated from cross-sectional information for 3-D surfaces. It is found that the depth of fill，where the damage of roof-tiles of wooden houses occurred，ranges between 5 to 15 meters. 広島工業大学 2005-02 jpn departmental bulletin paper VoR https://it-hiroshima.repo.nii.ac.jp/records/705 http://ci.nii.ac.jp/naid/40006641292/ http://ci.nii.ac.jp/naid/40006641292/ AA11599110 13469975 広島工業大学紀要. 研究編 39 113 117 https://it-hiroshima.repo.nii.ac.jp/record/705/files/kenkyuhen39113.pdf application/pdf 1.5 MB 2023-03-30
