山区地形起伏不平,给电阻率法勘探带来严重的地形影响.为了对实测资料作出正确的推断解释,必须进行地形改正.在电阻率法工作中均用点状电极供电和测量.计算点源电场受实际地形的影响是极为困难的,所以过去通常是用土槽或水槽实验来模拟.由于造型繁琐复杂,实验精度不高,以致这种模拟方法在实际中应用不广.在解释山区电测结果时,往往借用线源电场的理论计算(或模拟实验)对点源电场所测资料的地形影响作近似的改正.但是点源电场和线源电
Uneven terrain in the mountainous area has serious terrain impact on the resistivity exploration.In order to make the correct inferred interpretation of the measured data, the terrain correction must be carried out.When the point source The electric field is very difficult to be affected by the actual terrain, so the past is usually simulated by soil trough or sink test. Due to complicated shape and poor experimental accuracy, this simulation method is not widely used in practice. As a result, the theoretical calculations (or simulations) of the source electric field are often used to approximate the topographic effects of the data measured by the point source electric field, but the point source electric field and the source electric source
