| 摘 要： | 施甸5．9级地震震源浅导致了其震害偏重，而特殊的场地条件则导致许多烈度异常区（点）的产生。概述了施甸县历史地震的情况，介绍了旋甸5．9级地震震区自然根貌和场地特征，以近百年现场调查点资料为基础，将影响震害的四种主要因素，按其对震害影响程度的轻重分类，分析了该次地震的震害分布特征与异常区的场地特征，结果表明，在影响震害的诸多场地因素中，以地基土特性的影响最重。

| Abstract: | The Shidian earthquake generated comparatively serious disasters due to its shallow source and the special site conditions led to a lot of anomalous areas of intensity.The historical earthquakes in Shidian county are outlined and natural situation and site features in the earthquake area of the Shidian earthquake are presented in the paper.Based on the spot investigation of the data coming from nearly 100 sites,classifying of the four factors influencing the earthquake disasters according to their influence to the earthquake disasters is made and the distribution characteristics of the earthquake disasters and site characteristics in the anomalous areas are analyzed.The results show that foundation soil has the largest influence to the earthquake disasters among all site factors influencing the earthquake disasters. |
