| 摘 要： | 通过实测及几百孔钻孔的资料对比,研究直流电测深在浅层探查时曲线的AB/2与h的关系。由于电测深实测时,电极距按一定间隔布置,电测深曲线呈折线形。在混凝土厚度测定和最大深度10m的浅层探查时,反映下层电介质的曲线转折点的AB/2=h。

| Abstract: | The author has researched the relation between AB/2 and h of resistivity sounding on shallow investigation by means of contacting between measuring curves on objects and boreholes. The measuring curves on objects assume brokenline form, because their distance of the electrodes should be arranged by regular intermission when measuring on field. The AB/2 of turing points reflecting lower stratum is equal to h, depth of stratum. |
