摘要
根据建筑场地地震安全性评价工作的要求,结合实际工程讨论了场地地震安全性评价工作的技术思路、区域及近场区地震地质调查、地震活动性分析、地震地质背景、地震动衰减关系、地震危险性概率分析、场地地震动设计参数的确定等。经研究认为,在研究区域中存在发生七级左右地震的地质背景,本场地土类型为中软场地土,建筑场地类别为Ⅲ类。在研究中同时得到的场地设计地震动参数,可供设计部门参考。
According to the national request of seismic safety evaluation of engineering site, the evlution technique, seismic geological investigate, seismicity analysis, seismic geology background, attenuation relationship of seismicity of solid rock, seismic risk analysis with probability, the design parameters of ground motion etc. are discussed in detail by combining an engineering instance. The research suggests that the dangerousness is existent for taking place 7 degree earthquake according to the geology background; The soil type of the site is medium soft and its category is Ⅲ. At the same time, design parameters of ground motion are obtained, and they can be provided to the design section as references.
