自然电场法勘测地下水流向的极差校正

THE RANGE CORRECTION IN THE APPLICATION OF SPONTANEOUS ELECTIC FIELD METHOD TO THE DETECTION OF GROUNDWATER FLOW DIRECTION

总结了在实际工作中运用自然电场法中"8"字形观测法测量地下水流向时,对常规误差进行修正的经验,讨论了初始极差的产生因素、影响程度和处理方法,对后期资料处理中的补偿方法进行了探讨。

This paper has summed up the experience acquired in the correction of traditional errors in applying '8'shaped observational technique of the spontaneous electric method to measuring the flow direction of groundwater, and discussed such aspects of the initial range as reasons for its generation, degree of its influence and the tackling technique. The compensation method in late stage dataprocessing is also dealt with in this paper.
