| 摘 要： | 非构造型水库地震具有震级小、震源浅、烈度高的特点,研究其烈度衰减对库区地震地质灾害的预测与防治具有重要的意义。根据三峡库首区近年地震实地科考原始烈度资料,选择椭圆衰减模型并对其进行二元回归分析,得到非构造型水库地震的烈度衰减关系。并与原有构造型水库地震烈度衰减关系进行比较。结果可供库区地震危险性分析与地震小区划使用。

| Abstract: | Non-tectonic reservoir earthquakes have the characteristics of smaller magnitudes,shallower focus and higher intensities compared with natural earthquakes.The research on the intensity attenuation of non-tectonic reservoir earthquake is important to prediction and prevention of geological hazards caused by earthquake.Using the attenuation data of non-tectonic earthquake in the head region of Three Gorges reservoir in resent years based on the elliptic attenuation model, which is analyzed with bivariate regr... |
