摘　　要：为了减轻地震灾害对城市的影响,保证社会经济的可持续发展和人民生命财产安全,从地理位置、地震强度和灾害损失等方面分析了我国城市面临的地震风险,在总结城市震害的基础上,归纳了地震对城市的破坏作用和影响,梳理了城市场地条件对城市震害的影响,通过震例分析,对城市地震灾害形成的成因进行了分析和讨论,城市的建设需要选择抗震有利地段,避开不利地段,并提出7条减灾途径,在规划、加固、风险排查等方面尽可能降低地震对城市造成的影响。In order to reduce the impact on the city earthquake disasters,to ensure the sustainable development of social economy and people's life and property safety,from the geographical position,the respect such as earthquake intensity and the disaster loss analysis for the earthquake risk in our country,on the basis of summarizing the urban earthquake damage,summarizes the earthquake damage to the city function and influence of combed the city site conditions affecting urban earthquake damage.Through the analysis of earthquake cases,the causes of the formation of urban earthquake disasters are analyzed and discussed.In the construction of cities,it is necessary to choose the favorable earthquake-resistant areas and avoid the unfavorable ones,and seven ways to reduce the impact of earthquake on cities are put forward in terms of planning,reinforcement,risk investigation and so on.
