摘要
对甘肃省3口井流量的多年旬均值数据作了线性趋势分析处理,用1.5倍剩余标准差作为异常分辨控制线,研究了1985年6月24日宕昌5.0级地震、1987年1月8日迭部5.9级地震和1987年10月25日礼县5.1级地震前清水井、礼县井和成县井的异常形态和异常过程,给出了甘肃井网中流量井反映地震的能力明显高于水位井这个基本事实。
In this paper,we have computed the flow data of ten-day mean values for three wells in Gansu province by means of the linear trend analysis,and studied the anomalous shapes and process of the wells before Dangchang earthquake of magnitude 5. 0 on Jun. 24,1985,Diebu earthquake of M = 5. 9 on Jan. 8,1987 and Lixian earthquake of M= 5. 1 on Oct. 25,1987 by 1. 5 times residual standard error of observational values as a warning line of anomaly. The basic fact is that flow wells are more sensitive than water level wells in reflecting the anomaly of earthquakes in the network of the wells in Gansu province.
