| 摘 要： | 具有水平-垂直界面的岩层,在特定条件下,其纵向视电率测深曲线与直立层的等值。引入代替层概念,把二维复杂地电断面转化为直立代替层,从而应用直立层的公式计算二维复杂地电断面的视电阻率测深曲线。

| Abstract: | The vertical resistivity sounding curve over an earth with both verticaland horizontal interfaces under some special conditions is equivalent withthat over a vertical layer earth. So the idea of replacement layer isintroduced. A two-dimensional complicated earth is treated as a verticallayer earth, and the apparent resistivity sounding curve for the former canbe approximately calculated by using analytical expression for the latter. |
