摘要

汶川8.0级大震流体前兆异常的提取,采用了严格的定性与定量相结合的方法。运用"同一化"思路和从属函数等判定方法,处理川滇等地区的水位、水氡观测资料。介绍了5个典型的流体前兆异常实例,并对其特征进行归纳。初步研究结果表明,汶川地震的流体趋势前兆异常变化是明显的,这些异常的一个显著特点是,其变化特征与与我国其他强震前的异常相似。
Some precursory anomalies of subsurface fluid before the Wenchuan 8.0 earthquake was extracted by combining strict qualitative and quantitative method.The data of water level and radon changes in Sichuan and Yunnan provinces had been analysed according to the idea of "identity" and the method of subordinate function.This paper gave an introduction and the preliminary results of characteristics of five typical examples which showed precursory anomalies of subsurface fluid.It is obvious that the trend anomaly of subsurface fluid appeared before Wenchuan earthquake,and that these anomalies are similar to those of other strong earthquakes in China.
