| 摘 要： | 分析了鄂尔多斯地块南部和渭河盆地构造的空间分布特征，认为鄂尔多斯地块南部存在3条NW向隆起带，渭河盆地内部存在3个近EW向斜列的次级沉降中心，这些隆起带与次级沉降中心及其间的横向隆起共同组成了立交构造，分析了渭河盆地内部及其周边地区历史地震和现代地震的空间分布，发现立交构造对盆地内地震活动有着较强的控制作用。 |

| Abstract: | On the basis of field investigation and former studies,the geological structures and seismicity in Xiaolangdi reservoir and its adjacent area are analysed.It is considered that the geotectonic background is complex and seismicity is relatively week in the area.By using probabilistic statistic method,logic information method and gray cluster method, possibility and magnitude of induced earthquake of the Xiaolangdi reservoir are forecasted.The result shows that there is the possibility of the induced events,especially in the middle segment of the reservoir and the maximum magnitude could be 5.0. |
| Keywords: | Xiaolangdi reservoir Reservoir induced earthquake Probabilistic statistic method Logic information method |
