摘要
地震震害分布与地质构造紧密相关。通过对1976年唐山7.8级地震震害详细调查数据进行整理、筛检,围绕唐山断层带区域,选择1 130个自然村的震害数据,完成地理信息数据库录入,建立唐山地震震亡率、建筑物倒塌率分布图。在此基础之上,运用地理信息系统空间分析方法进行震害分布特征研究,并结合唐山市活断层探测最新成果,探索区域地质构造对震害分布的控制作用。
Seismic damage distribution is closely related to geological structure. Based on sorting and screen- ing of detailed seismic damage investigation data around Tangshan fault zone, seismic data of 1130 villages are cho- sen to finish the geography information database and establish the distribution maps of mortality and the ratio of col- lapsing houses by Tangshan earthquake. Then, the seismic damage distribution features are studied by using spatial analysis method of Geographic Information System. Combined with the latest achievements of active fault detection in Tangshan City, the control effect of regional geological structure on seismic damage is explored.
