对地下水动力学特征的观测与研究,是地震前兆监测的重要方法之一。地下水动力学研究中,利用地下水测年方法,可以对地下水的补给、径流特征及更新能力作出定性和定量的分析。本文介绍了近年来国际上常用的地下水测年方法,总结了前人在该领域的主要研究进展,重点分析了地下水更新能力与地震前兆信息的关系、地下水运动规律与地震构造活动的关系以及地下水浅层补给与异常干扰排除的方法等。已有的研究成果表明,地下水年龄的测定与分析方法对于了解监测点映震能力、评价构造活动与地震活动程度以及在观测资料异常变化的现场核实等方面,可以发挥重要作用。

[Abstract]
It is a significant method to monitor and study on the dynamic characteristics of groundwater for earthquake monitoring and prediction. For the research of groundwater dynamics, groundwater dating can provide quantitative basis on the characteristics of groundwater recharge and runoff as well as the renewal capacity. This article illustrates the methods used globally and summarizes the main advances and achievements in groundwater dating. It also focuses on the relationships between groundwater renewal capacity and seismic monitoring, groundwater movement and seismic activity, shallow groundwater recharge and abnormal interference elimination. The studies show that groundwater dating plays an important role in water-rock interaction,geological tectonic and seismic activity evaluation. Therefore,groundwater dating can be widely used to monitor and analyze the seismic information within underground fluid in the near future.
