摘要
提出了一个基于GIS技术的建筑物震害空间分布模拟方法,该方法首先利用GIS的模拟活化技术把地震影响场,建筑震害预测等分析模型形成可供空间分析使用的二次数据,并纳入城市基础数据库之中,构成综合基础数据库。然后利用GIS把多重空间数据进行空间复合,给出城市建筑物震害的空间分布及其统计特征,并识别出城市建筑物的重灾区。最后利用东营市建筑区为例,说明该方法的实用性和有效性。
This paper presents a method of spacial distribution simulation of seismic damage of urban buildings. Firstly, the intensity attenuation formulation and analysis model of seismic damage to the buildings can be synthesized, and the derivative database using special analysis technology GIS is formed. Then the special distribution and statistical characteristic of the seismic damage of the urban buildings can be graphed. Thus the critical seismic damage area can also be identified. As an example, the special distribution of the seismic damage to the buildings in Dong Ying city illustrates that the method presented in the paper is practical and efficient.
