水库诱发地震研究进展

Research progress on reservoir induced earthquake

水库诱发地震问题不仅是学术界需要科技攻关的难题,也是能够引起社会关注的热点问题。本文通过对国内外水库诱发地震震例的收集,初步分析了水库诱发地震与水库坝高、库容、岩性和地震活动背景的关系;对水库诱发地震的特点、成因分类、库水作用和预测方法进行了全面阐述;就现阶段水库诱发地震机理、波谱特征研究的方法和存在的问题进行了总结;介绍了水库诱发地震监测发展历程和最新数字化监测技术;提出了今后水库诱发地震研究的重点和所采取的技术手段。本文可为继续深入研究水库诱发地震机理提供参考。

The reservoir induced earthquake is not only a difficult problem for academic circles to tackle,but also a focal issue that attracts the attention of the society. In this paper,the relationship between reservoir induced earthquake and dam height,reservoir capacity,lithology and seismicity background is preliminarily analyzed by collecting seismic examples of reservoir induced earthquakes at home and abroad. The characteristics, origin classification, reservoir water function and prediction method of reservoir inducedearthquakes are comprehensively expounded. The methods and problems of reservoir induced seismicity andspectral characteristics are summarized. The development history of reservoir induced seismological monitoring and the latest digital monitoring technology are introduced. The key points and the technical measuresfor reservoir induced seismicity in the future are put forward. The paper provides a reference for furtherstudy of the mechanism of reservoir induced earthquakes.
