对比高密度电法中的各种常用装置对探测目标的电场响应,为工程水文地质勘查提供勘查经验。本文中,首先分析了温纳装置、偶极装置、微分装置、施伦贝尔1和施伦贝尔2的原理。然后利用这几种方法进行了野外物理试验,剔除了飞点,通过视电阻率拟断面作为反演的初始模型断面,利用最小二乘拟合方法分别算出了各个方式下的电阻率分布反演图。通过对同一条地质剖面的五种方法的结果进行比较分析,表明:在同一地质模型条件下,各种方式基本上都能反映异常,但其分辨率严重依赖于供电极距;五种装置各有特点,温纳装置横向分辨率较高,偶极装置纵向分辨率比温纳装置好,施伦贝尔装置在横向不均匀体上反映灵敏,微分装置相对其它效果一般。 Comparing the electric field response of various commonly used devices in high density electric method to the detection target, providing exploration experience for engineering hydrogeological exploration. In this paper, we first analyze the principle of the Winner, dipole, differential, Schlumberger 1 and Schlumberger 2. Then the field experiments were carried out by using these methods. The flying points were eliminated and the resistivity profile was taken as the initial model cross section through the apparent resistivity section. The resistivity distribution inversion under each mode was calculated by the least square fitting method Figure Through the comparison and analysis of the results of the five methods of the same geological section, it shows that under the same geological model, all kinds of methods can basically reflect the anomaly, but the resolution is seriously dependent on the electrode pitch; It has the characteristics of higher lateral resolution of the WENER device, higher longitudinal resolution of the dipole device than that of the WENNER device, and the Schlumberger device responds sensitively to the lateral unevenness. The differential device is generally more effective than others.
