| 摘 要： | 通过一工程勘测实例,分析了高密度电法中常用的Wennerα装置和四极测深装置(Wenner-Schlumberger)的适应特征.认为,勘测浅层(如15m内)的采空区或地质灾害异常体时,以四极测深装置为好,对深层(如50m以上)则用Wenner装置为好.地层性质和饱水状态不同地区所测的视电阻率,即使在同一深度(或层位)上,其所表达的意义是不同的,不能用这种资料来作平面等值线图并以此图件来寻找采空区或其它地质灾害异常体.

| Abstract: | By use of one example of actual survey,the characteristics of the arrangement of Wenner and Wenner-Schlumberger(4-Poles depth survey) in the high density resistivity survey system are analyzed.It is thought that it is a better means of 4-Poles depth survey arrangement to measure the shallow(h<15m) mined-out area or anomalous geological bodies.But for the deep(h>50m) mined-out area or anomalous geological bodies.The Wenner arrangement is better.The meaning of resistivity is different even in the same depth but in different districts where the stratigraphic or the degree of saturation is different.It is no means to use these data to make contour diagrams or use these diagrams to find mined-out area or anomalous geological bodies. |
