摘　　要：本文通过对高密度电阻率法勘探中的长测线多排列数据进行连接处理,实现了同一测线采用同一套参数的规范化处理,克服了因不同排列采用不同参数处理而导致假异常和信息丢失等弊端,同时解决了在成像时,因各个电性剖面的色标值不一致,剖面坐标与实际桩号对应不直观,导致对整个区域的电性趋势认识产生误导的问题.从实例处理来看,能为整个勘探区提取更丰富的电性信息,不但突出了整条测线的地下电性趋势,更客观、更全面地把握和认识勘探地区的电性分布规律,而且从宏观上把握了一些比较隐蔽的地质现象.We have carried out high density resistivity data processing standardization for one line with one suit of parameters through long line and multi-array data linkage processing, conquered the abuse of false anomaly and information lose for multi-array with different parameters, and resolved the problem that the disaecord of color bar with different array electric property profile and no illustration for the coordinate of profile with the chainage. From true data processing, it can acguire abundant electrical information for all exploration area, which can not only reveal wellmarked the electricity tendency of this distract under the line, hold and recognize the distribution of the electrical property objectively and completely, but also grasp some subtle geological information.
