地下含水层氡浓度和水位实时动态的潮汐现象与数字化单井综合观测

Real-time dynamic tidal phenomena of groundwater radon density and water level and their digitalized compre-hensive observation in a single well

在宁德地震台进行的地下水数字化单井综合观测实验中,采用“恒流式”单井综合观测方法,配套相应的技术系统,实现了对地下含水层氡浓度和水位实时动态的连续综合观测,而且记录到两者具有与固体潮相对应的同步性半日波微动态。分析认为,这一方面为地下水有关测项预报地震力学基础的研究提供了新的观测事实;另一方面,为试图通过综合观测以期有利于识别干扰与地震前兆信息研究思路的实践提供了一种新途径。

In the experiment of digitalized comprehensive observation of groundwater in a single well at Ningde Seismic Station, by using ＂constant flow＂ observation method in a single well, a continual observation of groundwater radon density and the real-time dynamic water level is realized with a complete-set relative technical system, and it is recorded that both have an in-phase half sunny wave dynamic matching with object tide. The analysis holds that it provides,＂ on one hand, a new observation fact for a basic study of forecasting seismic dynamics concerning the underground water, and, on the other hand, a new way to explore a research thinking, which tries to use the comprehensive observation and find a useful identification of interference and information before an earthquake.
