摘要
汤参一井水氡2008年度出现明显异常,本文进行了深入地分析研究。通过对比研究该井其他测项以及与其相邻的台站水氡资料,发现其他测项没有出现与汤参一井水氡同步大幅度异常,排除了汤参一井地下地应力显著改变的可能性,认为汤参一井水氡异常主要原因是由于其周围大量的地热井开采导致汤参一井地下水在流出地面越来越慢所致。
We intensively analyze the anomaly condition of subsurface fluid （radon） at Number One Well Tangcan （Tangcan well） in 2008. By the contrast and study of its other test items and information of the subsurface fluid （radon） in its contiguous seismic station, we do not find synchronous substantial anomaly of other test items, so we exclude the probability that the underground stress at Tangcan well change obviously. We think its main reasons for the subsurface fluid （radon） anomaly at Tangcan well lie in the many geotherm wells exploited in its contiguous area, and that underground water of Tangcan well outflows slower and slower.
