The distribution of seismic buried personnel is an important basis for scientific and effective post-earthquake emergency rescue.To evaluate the distribution of buried personnel caused by the destruction of buildings during earthquake,a relationship model among urban population,indoor rate,and buildings was established at a spatial scale of community.Combined with seismic damage assessment methods of buildings,a rapid assessment model of seismic buried personnel was constructed in this paper.Then,a case study of Tianjin urban area was taken to estimate the amount and distribution of seismic buried personnel under various intensities.Results showed that the night is the high-risk period for seismic buried accidents,and four areas (residential,universities,resident service,and hospitals) have high risk of seismic burial.Furthermore,attention should be fixed on primary and secondary schools in daytime on weekdays.
