摘要
对大华北地区地下流体资料进行梳理,筛选连续性好、相对稳定且存在趋势转折的资料进行趋势转折变化分析,根据转折时间点和形态进行时空特征分析,并提出了趋势转折的定量分析方法。结果显示,大华北地区流体趋势转折的测项数在2006年和2011年出现明显增多的现象,此现象与2006年文安5.1级地震和2011年日本9.0级地震的影响有关。
We select out continue and relatively stable underground fluid data that has trend turning in great North China Area to analyze its changing characteristics.According to the turning point and form,we find out the temporal-spatial characteristics and then put forward a quantitative method for tread turning analysis.The results show that the fluid trend turning changes increased rapidly in the great North China Area in 2006 and 2011,this phenomenon may be related to with the 2006Wen'an M_S5.1 earthquake and the 2011 Japan M_W9.0 earthquake respectively.
