本文利用不同深度观测孔的资料与距太原300公里内大于5级地震的对应关系作一些分析研究.一、专用地震孔组的水文地质条件J_3孔组位于太原新生代断陷盆地的北端,太原市迎新街北一条隐伏断裂的北端.J_3孔深30米,观测第四系全新统和上更新统潜水动态,水位埋深6米左右.J_3~1孔深110米,观测67—98米第四系中更新统承压水动态,水位埋深20—28米.J_3~2孔深304米,观测216—296米第三系承压水动态,水位埋深15—24米.J_3~3孔深494米,观测42米以下的石炭系裂隙承压水动态,水位高出地表8米左右.二、分析震例,总结经验深入研究震例,是正确的认识地震与摸索预报方法比较有效的途径.
In this paper, we analyze the relationship between the data of observation holes with different depths and the earthquakes larger than M≥5 within 300 km from Taiyuan.First, the hydrogeological conditions of special seismic hole group J_3 are located at the northern end of Taiyuan Cenozoic rift basin, Yingxin Street north of a concealed fracture of the northern end of .J_3 hole depth of 30 meters, observation of Quaternary Holocene and Upper Pleistocene diving dynamics, water depth of about 6 meters .J_3 ~ 1 hole depth of 110 meters, the observation of 67-98 meters Four series of the Pleistocene hydrostatic pressure, the water depth of 20-28 meters. J_3 ~ 2 holes and 304 meters deep, observed 216-296 meters Tertiary pressure water dynamic, water depth of 15-24 meters .J_3 ~ 3 Hole 494 meters deep, observed under 42 meters Carboniferous fracture confined water dynamic, the water level is about 8 meters above the surface 2. Analysis of earthquake cases, lessons learned Experience in-depth study of earthquake cases is the correct understanding of earthquake and groping prediction method is more effective Way.
