深圳市高层建筑地震安全指数判定系统
|
摘要
以深圳市高层建筑为研究实例,介绍了香港大学的城市灾害损失评估及应急反应管理系统,并采用此系统内置的建筑易损性分析模块,结合泛珠三角地区灾害危险性概率模式,场地特征及高层建筑实地调查分析结果,从建筑安全性角度对深圳市的标志性建筑进行危险性分析,进而对深圳市应对突发性灾难事件的管理建设提出建议。作为应用实例,模拟一定概率条件下的灾难事件发生时的建筑物损坏情况,归纳出高层建筑的损坏模式,总结深圳市高层建筑的安全性隐患,提出目前防灾减灾急需实施的相应步骤:建议在一元化的城市灾害预警和应急指挥体系下,整合各个灾种防灾减灾管理部门的资源,以科学分析软件为灾情模拟和决策预案制定的工具,使危机处理的理念由领导决策型转向科学分析型,加强城市应对面对突发事件的能力,保障经济与社会的持续稳定发展。
A Disaster Loss Assessment and Emergency response System for urban Pan-Pearl River Delta Area has been developed based on Geographic Information System(GIS).This expert supporting decision system combines disaster hazard analysis,vulnerability analysis and loss estimation models for urban disaster mitigation and emergency response.A case study has been conducted for high-rise building in Shenzhen-a rapid developing urban area.Supported by the analysis modules of the system,which provide tools for regional hazard analysis and structural vulnerability index assessment,a sidewalk investigation has been completed and safety estimation on urban benchmark high-rise buildings has been performed.Effective strategies for disaster mitigation and emergency management for the city of Shenzhen have been provided to guarantee continuous and stable economic/social development.
