| 摘 要： | 文中从高密度电法系统的发展、电极排列方式，反演方法及应用等方面，介绍了高密度电阻率法的应用研究进展。说明了高密度电法仪器从集中式到分布式，电极排列方式为适应地形变化等因素的影响，由某一种排列方式发展到组合排列和自定义排列方式。反演方法由早期的最小二乘反演发展到佐迪反演、基于born近似反演等反演方法，且从一维发展到三维，甚至四维。反演软件也从二维反演发展到三维反演，如德国DMT公司的反演软件从Res2DINV发展到Res3DINV，美国AGI公司的Earthimnge反演软件可以进行水域、跨孔高密度电法发演。列举了高密度电法近几年来在多个领域的应用概况，最后，文章总结出高密度电法仪器的发展方向为：提高发射机功率，增大供电电流，以及增加排列长度，提高仪器通道数量；带地形的非线性共轭梯度三维反演具有需要内存小、计算速度快，可以更好的定位鼻常体的幸间位置等优点．将会得到受为广泛的应用．

| Abstract: | This paper reviews the research progresses of the high-density resistivity method, including the development of the high-density resistivity system, electrode arrangement ways and inversion methods, as well as the development from centralized to distributed instrument deployment. The electrode arrangement developed from one arrangement mode to combined permutation and self-defining mode in order to adapt to changing terrains and other factors. The inversion method was mainly the least square inversion in the early time, and later replaced by the Zohdy inversion and Born approximate inversion method, and developed from 1D to 3D, and even 4D. The inversion software developed from 2D to 3D, for example, the inversion software of DMT Company of Germany developed Res 2DINV to Res 3DINV. The inversion software Earthimage of AGI company of the USA can be applied to data processing and inversion in water areas and cross-hole high density resistivity inversion. We present examples of the application of the high-density resistivity in many fields in recent years. In the end, this paper points out that the development trend of the high density resistivity method is increasing the transmitter power, increasing the supply current, increasing spread length and increasing the number of instrument channels. The three-dimensional nonlinear conjugate gradient inversion with topography has the advantages of demanding less memory, fast calculation, being capable of positioning the location of anomalous body. It would be more widely applied. |
