为改善山东泰安市岱岳区北部下港乡的饮水条件, 运用视电阻率联合剖面法分析了研究区低电阻率的异常特 征, 推测出低阻正交点异常与小型裂隙发育有关, 从而确定NNE 向异常体为裂隙破碎带; 在此基础上通过三极电 测深法分析了低阻/ U 型0 异常特征, 推测出以530/ 3 测点为中心的地下水富集区, 确定深度70~ 250 m 基岩裂隙发 育, 富水性强, 水量丰富; 最终选择530/ 3 测点为孔位点, 同时对其进行成井施工探水, 最终孔深为194 m, 涌水量为 168 m3/ d。研究结果不仅解决了用水问题, 同时证明综合电法是一种可行、有效的找水勘探手段。

In or der t o impro ve t he dr inking w ater conditio ns o f Xiag ang v illag e in the nort h of Daiy ue district of Taian city of Shando ng Pr ov ince, the abnormal characteristics of lower resistiv ity wer e analyzed using the appar ent r esistivity combined pro2 files method in this paper. T he r esults showed t hat the fr acture development is related to the abno rmal character istics o f low re2 sistance po int of intersectio n, which can determine the fissure crushed zone w ith NNE dir ect ion. On the basis, the abno rmal char acter istics of low er r esist ivit y U2type w ere analy zed using the tr i electro de sounding method, w hich speculates the g roundw2 ater rich area in center point o f 530/ 3 and sugg est s that bedr ock fissur e dev elops at the depth of 70 to 250 meter s. Finally, the po int of 530/ 3 w as used as the drilling point, and geo physical ex plo ration w as per formed to det ermine that the point is 194 me2 ter s deep and has an aver age daily water product ion o f 168 m3 . The study not only solves the water supply pr oblem, but also pr oves that the integr ated elect ric method is a practical and effect ive w ay fo r g roundw ater ex plo ratio n.
