城市地震压埋人员分布评估研究——以天津市区为例

地震压埋人员分布是震后科学、有效地开展应急处置和救援的重要依据。针对地震中建筑物破坏造成的人员压埋，从人口分布和在室率着手，在社区级空间尺度上分时段建立人口数量、在室率和建筑物的对应关系；结合建筑物震害评估方法，构建地震压埋人员快速评估模型，并预评估天津市区各烈度下地震压埋人口的数量和分布情况。结果显示，夜间是发生地震压埋的高风险时段，住宅、大学、居民服务类和卫生医疗建筑是地震压埋高发区域，工作日白天应重点关注中小学。

Assessment of seismic buried personnel in urban area: a case study of Tianjin urban area, China

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.
