Seismic risk assessment of housing by using geographical information

为了阐明地震对房屋的破坏机理和发展灾害预测方法，本研究收集了中越地震和中越树地震中受灾房屋的受灾证据，并分析了地震烈度与房屋损坏的相关性。通过处理内陆地震和沿海地震造成的地震灾害，研究了尽可能排除震害地点的房屋灾害模型。由于房屋受损数量不适合定量估计房屋损失，引入房屋损失率进行相关分析。最后，通过将地面分类分为四类，提出了房屋损伤率与地震烈度的关系

For the purpose of elucidation of damage mechanism and development of disaster prediction method for housing by the earthquake, this study collected the afflicted proof of the affected houses in Chuetsu earthquake and Chuetsu-oki earthquake and analyzed for correlation with seismic intensity and house damage. By handling two earthquake damages caused by inland and coastal earthquakes, a housing damage model was investigated by excluding the locality of earthquake damage as much as possible. The housing damage ratio was introduced and employed in the correlation analysis since the number of damaged houses is not appropriate to quantitative estimation of housing damage. Finally, the relationship between housing damage ratio and seismic intensity was proposed by arranging the ground classifications into four groups
