摘要
在特大城市开展地震小区划和震害预测在我国是一次新的尝试。广州密集的建筑物群、到处耸立的高楼大厦、横贯市区的高架路桥和立交桥,是其它中小城市不具有的。海量的数据资源、复杂的空间结构给地震灾害分析、空间数据处理带来了诸多挑战,在数据资料调查收集、分析处理技术、信息系统开发平台等方面要求更高,加深了研究难度。介绍了广州市部分城区地震小区划和震害预测的工作区概况、研究方法和内容及成果特点。
Developing seismic micro-zoning and seismic damage prediction in mega-city is a new attempt in our country. In Guangzhou the crowded building groups, the towering tall buildings, crossing urban district the high-flying highway bridges and multi-level crossing bridges are everywhere, which have not been in the middle and small cities. The macro- data resources, and complex spatial structures have brought many challenges to the space data processing and the analysis of the earthquake disaster. The requirements of the technical development platform, the data bank administration technology, and the data analysis and processing are high, and thus the research difficulties about cases above are increased. This article has introduced the general situation of the work area survey, the research methods and content, and the characteristics of achievement of the seismic micro-zoning and the seismic damage prediction for some districts in Guangzh
