摘要
蒲江川-11井始建于1982年,是四川省重要的水位观测井,位于蒲江—新津—成都—德阳隐伏断裂和大兴隐伏断裂附近,近年来,该井观测环境优良,干扰小,是一口理想的水位观测井。自1982年投入观测以来,对川西地区的地震预测发挥了较好作用,特别是2002年以来,观测到了一些有益的突跳异常,并较好地对应了300 km内的4.5级以上地震。本文对川-11井异常进行了初步分析。
The 11^th observation well of Pujiang was set up in 1982. It is an important observation well of groundwater level. The sub-surface structure fault of Pujiang-Xinjin-Ehengdu-Deyang is near the well. Recent years the environments of observation is improved and interfere to the observation data is small. Since 1982 the observation data is useful to earthquake prediction. The quick changes are relative to the earthquake eceurred 300 kilometers away in the western part of Siehuan province. We discuss the 11 times abnormal changes.
