本文根据近年来我们在现场开展水氡干扰因素试验研究的结果,集中论述了当前视为较好临震指标的水氡突跳中的各类干扰因素及其原因。指出气象因素(如降雨等)、地质因素(如滑坡)、水文地质因素(包括水动力条件的改变)、水点自然环境因素(包括出露条件)以及某种偶然因素等都可程度不同的引起水氡突变,必须因泉(井)制宜的开展试验,掌握并排除干扰,才能有效的突出地震异常。我们还就识别、排除干扰的方法作了探讨,提出在构造区域范围内布点,开展多点水化(氡、气和其他化学组分)综合观测、试验、研究,是识别干扰和判断地震异常的有效方法。
In this paper, based on the results of our experimental study on radon interference in the field in recent years, we focus on all kinds of interference factors and their causes in current radon sudden jump, which is regarded as a better indicator of temporary intrusion. Pointed out that the meteorological factors (such as rainfall), geological factors (such as landslides), hydrogeological factors (including changes in hydrodynamic conditions), water points of natural environmental factors (including the exposure conditions) and some of the accidental factors may vary Water radon mutation caused by the spring (well) should be carried out appropriate tests to master and remove interference in order to effectively highlight the earthquake anomalies. We also discussed the methods of identifying and eliminating interferences. We put forward that we should lay out and organize multi-point hydration (radon, gas and other chemical components) comprehensive observation, experiment and research within the tectonic region to identify interferences and determine seismic anomalies Effective method.
