井水位前驱波普遍性问题的探讨
|
摘要
以山西、河北、内蒙等地5口映震能力较强的地下水位观测井为研究对象,对井水位前驱波普遍性问题进行了探讨。结果表明,强震井水位前驱波现象较为普遍,其比例可达65.1%(41/63);相同地震不同观测井前驱波特征各不相同,同一观测井在不同地震前的特征也各异,这可能与不同观测井具有不同的井-含水层结构以及不同地震前有着不同的震源参数有关;与单井水震波相比,震前有前驱波记录的次数略低于水震波,其比例在39.7%～50.7%之间;震前有前驱波记录的观测井占研究区观测井总数的比例可达66.7%。
Taking as the study objects for the five observation wells of underground water level with high earthquake reflecting ability in the provinces of Shanxi,Hebei and Inner Mongolia,the paper studies and discusses the generality of the precursory wave of well water level.It is indicated that the precursory wave happens commonly before strong earthquakes,with a ratio up to 65 percent(41/63).The characteristics of precursor waves of different observation wells are different.Even for the same observation well,the characteristics of precursory wave for different earchquakes are different too,which may be the result that different observation wells have different well-water-bearing bed structures and different earthquakes have different source parameters.Compared with the single well water shake waves,the recording time of precursory wave before strong earthquakes is slightly less than that of the water shake waves,with a ratio between 39.7 and 50.7 percent.The number of observation wells with precursory wave recordings before earthquakes accounts for up to 66.7 percent of the total of observation wells.Except for its characteristics,the precursory wave of well water level has its generality both in terms of the recording times and space.
