【摘要】 根据格尔木台观测井的水文地质条件、水氡观测存在的主要干扰因素和年动态变化特征等方面因素,对格尔木地震台水井的水氡观测出现的趋势、突变异常进行了分析。结果表明,格尔木水氡趋势变化与气温有关、水氡突降与流量变化有关,更重要的是存在与格尔木水文地质条件有关的信息,反映了岩石应力—应变、区域构造和地震活动的相关信息。更多还原

【Abstract】 Based on the hydro-geological conditions around the well of Golmud seismic station,the main interference factors,such as the annual dynamic characteristics of water-radon and so on,and the trends and mutation abnormalities of water-radon observation of the well are analyzed in this paper.The analysis results show that the trends of water-radon are related to the temperature of water,sudden drops of water-radon and flow amount changes in Golmud well.More importantly,the trends and mutation of water-radon abnormality are related to the hydro-geological conditions around Golmud seismic station.These characteristics are related to the changes caused by rock stress-strain,the regional tectonic and seismic activity.更多还原
