【摘要】 为了了解供水系统中清水池及水处理池的抗震性能及震害特点,基于1975年海城地震、1976年唐山地震、1996年包头西地震和2008年汶川地震供水系统水池的震害资料,采用统计分析的方法,研究了水池的功能状态及地震破坏与地震烈度、结构形式、材料、场地土等因素之间的关系,初步给出了清水池和水处理池的地震易损性矩阵,并提出了提高水池抗震能力的对策建议。更多还原

【Abstract】 This paper studied the seismic performance and damage characteristics of clear water reserviors and water treatment cisterns in water supply system based on earthquake damage data of pools in 1975 Haicheng earthquake,1976 Tangshan earthquake,1996 Western Baotou earthquake and 2008 Wenchuan earthquake.The relationships of function status of pools and earthquake damage with some specific factors,such as earthquake intensity,structural form,material and site soil,were studied by statistical analysis method.Seismic vulnerability matrices of clear water reservoirs and water treatment cisterns were given.Countermeasures and suggestions to improve seismic performance of pools were proposed.更多还原
