地震地质灾害对广州市部分城区工程环境的影响分析

Analysis on the Influence of Seismogeological Disaster upon the Engineering Environment of Some City Zones of Guangzhou

通过震害预测研究,探明地震地质灾害源,应用地理信息系统掌握地震地质灾害源空间分布情况,分析其对工程环境的影响范围和影响程度,有助于政府制定防震减灾规划和城市建设与改造。针对广州市部分城区的地震地质灾害源、建筑物、生命线工程、地震次生灾害源的分布情况,应用基于GIS平台的防震减灾信息管理与地震应急辅助决策系统,分析了该区内地震地质灾害破坏对建筑物、生命线工程和地震次生灾害源的影响。结果表明,城市中的建筑物、生命线工程和地震次生灾害源不同程度地受到地震地质灾害的影响。

Through researching on earthquake disaster forecast, proving up the source of seismogeological disaster and applying GIS, we can know well its distribution in space, affecting range and disaster level. This is helpful for government to make the plan for protecting against and mitigating earthquake disasters and building and rebuilding the city. In view of the distribution condition of source of seismogeological disaster, buildings, lifeline engineering and secondary disaster in some city zones of Guangzhou, the information system for disaster reduction and assistant decision-making earthquake for earthquake emergency response based on GIS platform was used to analyze the influence on the buildings, lifeline engineering and secondary disaster by seismogeological disaster. The result shows that the buildings, lifeline engineering and source of secondary disaster are influenced to various degrees by seismogeological disaster.
