摘　　要：泰山群变质岩的地下水类型为风化裂隙水和构造裂隙水,风化带厚度及裂隙发育不均匀,裂隙水连通性差,储水空间有限,造成地下水富水性严重不均。根据变质岩的岩性、结构、构造,总结出风化壳蓄水构造、断裂带蓄水构造、岩脉蓄水构造、粗粒岩石蓄水构造;根据野外电测找水经验,在泰山群变质岩土地区,有低阻正交点、V形低阻异常、麻花低阻异常、半衰时窄幅单峰异常、宽幅单峰异常等富水构造特征,找水可取得明显的效果。The weathering crevice water and the structure crevice water are main ground waters in Taishangroup metamorphic rock. Because of the uneven weathering zone thickness, bad connectivity of the crevice water and limited store water space, the ground water of rich-water area is seriously uneven. According to the rock property, structure and rock-fabric, there exists the crust of storage structure conditions such as weathering rock, fracture zone rock, dyke rock, coarse grained rock and so on. By finding the low resistance orthogonal point, the unimodal abnormal ＂V＂ shape low resistance, abnormal twist-shape low resistance, unimodal abnormal curve of narrow width, unimodal abnormal curve of broad width and so on, in the field measures, seeking the ground water in the Taishan-group metamorphic rock is very successful.
