近几十年来,特别是近二十年来,随着人类工程活动的规模和领域的扩大,出现了伴生的新问题——诱发地震。水库蓄水、小规模的地面或地下采矿、处理废液、地热发电和石油开采及城市大量抽取地下水以及地下核爆破等都造成局部地震活动增强。由于诱发地震是伴随大型工程而发生的,且多发生于大型工程附近,所以即使5级左右的地震也应予以考虑。国内外学者对水库地震的预测提出过许多方法。本文介绍了预测水库地震的统计检验预测模式和两级模糊综合评判模式,并用实际水库震例进行了检验。
In recent decades, especially in the past 20 years, as the scale and scope of human engineering activities have expanded, new problems associated with it have emerged: the earthquake was induced. Increased local seismic activity has been caused by reservoir water storage, small-scale ground or underground mining, waste disposal, geothermal power generation and oil extraction, large underground extraction of groundwater from cities and underground nuclear explosions. Since induced earthquakes occur with large-scale projects and occur mostly near large-scale projects, even earthquakes of magnitude 5 or so should be considered. Domestic and foreign scholars have proposed many methods for the prediction of reservoir earthquakes. This paper introduces the statistical test prediction mode and the two-level fuzzy comprehensive evaluation mode for predicting reservoir earthquakes, and tests the results with actual reservoir seismic events.
