| 摘 要： | 本文从三峡库区区域地质构造、活动断裂及库区水文地质特点建立三峡库区区域地震模型;根据蓄水后岩石的库水与地质相互作用对该区水文地质及构造影响,对该区水库诱发地震进行理论分析,浅释了三峡库区水库地震孕震机理;以三峡遥测台网测震资料及宜昌台地壳形变手段在蓄水前后的监测的地壳动态变化特征为基础,对三峡水库诱发地震作了初步探讨及趋势分析.

| Abstract: | A regional earthquake model for the Three Gorges is set up according to the geological structure, active fault and hydrogeological characters. Based on the mutual relationship and influence between the reserved water and stone ground, as well as on the theoretical analysis of the potential earthquakes caused by the reservoir, the authors explain the seismogenic mechanism. On the basis of the data collected by Three Gorges Telemetering Station and the dynamic change characteristics summarized by Yichang Station before and after the water storage, the authors try to analyze the possible earthquake trends and reasons in the region. |
