摘要:
将地理信息系统(GIS)技术用于震害预测在国内外都有较为广泛和成熟的研究。大多数的研究都是基于二维GIS技术的应用,以图表的形式显示震害预测结果,不能够直观地显示建筑物空间特征。本文以砖混结构建筑为例,总结了不同震害等级的震害特征,将提取的震害特征和建筑物纹理合成,利用Google SketchUp三维建模和ArcGIS Engine开发实现震害三维显示。本文给出了利用三维模拟技术在震害预测研究中的一种方法和思路,旨在为震后应急救援、虚拟救援训练和地震科普教学等方面提供帮助。

Three-dimensional Building Damage Simulation Based on GIS
Gu Guoliang1),Jiang Lixin2)
Abstract:
GIS technology has been applied to building damage analysis around the world. However, most previous studies focused on the application of 2-D GIS technology, and the results from traditional earthquake damage prediction are displayed in 2-D figures and charts, which is incapable of demonstrating the 3-D spatial characteristics of buildings. Taking brick-concrete building as an example, we study the characteristics of building damage, and effectively combine the information of building textures and earthquake damage. Then, we apply Google SketchUp techniques to create building models and display them with seismic damage texture in the ArcGIS Engine software development environment. In this paper we propose a solid idea for 3-D simulation of earthquake damage, which is helpful in earthquake damage prediction, virtual emergency rescue practice and earthquake knowledge education.
