利用城镇地籍数据信息,基于GIS软件进行建筑物易损性和居民安全风险分析与应用研究。通过对某县城中最具代表性的一个街坊建筑物的易损性分析和居民安全风险分析实例应用研究,重点讨论并实现了利用现有数字化地籍图、城镇地籍数据库及土地调查记录等信息;并结合建筑物震害损失评估模型和人员伤亡预测方法,完成不同结构类型的建筑物在不同地震烈度条件下的破坏造成的经济损失评估和人员伤亡程度的预测,对城市防灾减灾进行辅助决策支持与评估。
The use of urban cadastral data information, based on GIS software for building vulnerability and residents of security risk analysis and application research. Through the application of a case study of vulnerability analysis and resident security risk analysis of a typical neighborhood block in a county, this paper mainly discusses and realizes the utilization of existing digital cadastral maps, urban cadastral database and land survey records. Combined with the building damage damage assessment model and the casualty prediction method, the economic loss assessment and the casualty prediction of buildings with different types of structures under different earthquake intensity conditions are completed, and the urban disaster prevention and mitigation is assisted Support and evaluation.
