| 摘 要： | 介绍了姚安6．5级地震震区地质概貌和场地特征。以100多个现场调查点资料为基础，将影响震害的四种主要因素，按其影响轻重分类，用震害指数分析了该次地震的震害分布和局部场地特征对震害的影响。结果表明，震区未形成震害异常区，但有震害异常点存在。在影响震害的诸多场地因素中，以地基土特性的影响最为严重。

| Abstract: | This paper has introduced the geological features and site characteristics in Yao'an M6.5 seismic area. There are four kinds of factors affecting seismic disasters based on the data collected in more than 100 point surveys. We have analyzed the disaster distribution and site influence to the seismic disasters by using index of seismic disaster. The results show that it does not form anomalous area of seismic disasters in the seismic area, but has anomalous points. The site soil is the most significant to influence the seismic disaster in many factors. |
