摘要:
对北川县城851栋建筑物的震害资料进行了现场调查,建立了建筑物震害数据库。提取了建筑物不同部位的纹理特征,建立了纹理特征数据库,编写了建筑物三维建模的流程和规则。基于CityEngine平台快速批量地建立了北川县城851栋建筑物的三维模型。采用遥感影像和DEM数据建立了北川县城区域的三维地形,结合建筑物三维模型构建了汶川地震前北川县城的场景。采用建筑物单体震害预测方法,计算分析了不同结构类型建筑物在不同地震烈度(Ⅵ~Ⅺ)下的震害指数和破坏等级。在CityEngine平台中用不同颜色渲染建筑物描述其破坏等级,建立了北川县建筑群三维震害场景。结果表明CityEngine三维快速建模技术比传统3ds Max三维建模技术效率更高,结合单体震害预测方法,可以快速模拟大规模建筑群三维震害场景。
Abstract:
The database of buildings’ earthquake damage characteristics was established, by surveying 851 buildings of Beichuan County which is loacated at seismic intensity Ⅺ area in wenchuan M8.0 earthquake. The texture characteristics was extracted from buildings, then the database was built. Moreover, the process and rules of three-dimensional (3D) building modeling was compiled. The 851 3D building models was batch established based on CityEngine. The 3D terrain of Beichuan County was modeled by using DEM data and remote sensing imagery. Meanwhile, the scenes of Beichuan County that is before wenchuan earthquake were assembled by the 3D building and terrain models. The various type buildings seismic damage index and status in different seismic intensity (Ⅵ~Ⅺ) were analyzed. Then, the building seismic damage status was described by different color in CityEngine software. Finally, the Beichuan County building agglomeration 3D seismic disaster scenes was built. The results show that, the CityEngine modeling technique is more efficient than 3ds Max technique in building agglomeration 3D modeling. The large building agglomeration 3D seismic disaster simulation can be quickly establish based on CityEngine and seismic damage prediction method of single building.
