| 中文摘要: |
| 本文在分析了小浪底水库工程地质、地震地质背景后，探讨了水库诱发地震的深入研究问题。首先分析了水库诱发地震前期预测和蓄水后判别的特点，阐述了水库区“天然地震本底” 的概念，提出库区天然地震本底研究是蓄水后判别是否属于水库诱发地震的基本依据，量化 的地震本底可以作为判别的主要标志之一。指出年频次、月频次、地震年释放能量、库盆及 邻区地震级-频度关系等指标可作为小浪底水库诱发地震的判别标准。 |
| 英文摘要: |
| The possibility of reservoir induced earthquake of the Xiaolangdi Project is studied on the basis of geology structure and natural seismic background analyses.The standard for discriminating reservoir induc ed seismicity is proposed.It is found that no irregular seismic activity that ex ceeds the discriminating standard has been occurred in four years since the impounding of the reservoir. |
