地形改正在山区电法工作中的应用

Application of Topographic Correction in Electrical Method Work in Mountainous Areas

通过2个山区(激)电测深勘查工作实例,对实测数据进行地形改正处理,采用带修正系数的供电极距的均方根为纵坐标绘制带地形的拟断面图,所反映的断面异常信息兼顾深、浅部地电体形态,可以对断面异常作出较为全面的认识和分析,方便对异常进行快速定性解释。

Through two examples of electrical sounding in mountainous areas,the topographic correction of measured data is processed,and the pseudo-sectional map with topography is drawn by using the root mean square of the distance between the supply poles with correction coefficient as the ordinate.The information of sectional anomalies reflected takes into account the shape of deep and shallow geoelectric bodies,so that the sectional anomalies can be made more comprehensive.Understanding and analysis are convenient for rapid qualitative interpretation of anomalies.
