| 摘 要： | 直流电阻率法已经被广泛运用于工程勘察中,但是复杂的地形一直影响着直流电阻率法的勘探精度。该文从非结构化网格剖分技术中的Delaunay三角剖分法出发,以起伏地形下的直流电阻率法反演成像为目的,结合工程实例,证明了将Delaunay三角剖分技术,应用到有地形起伏的直流电阻率法反演成像中是行之有效的。

| Abstract: | The DC resistivity method has been widely used in engineering exploration, but the complex terrain has always affected the exploration accuracy of DC resistivity method. Starting from the Delaunay triangulation method in unstructured mesh generation technology, taking the DC resistivity inversion imaging under undulating terrain as the purpose, combining with the project example, this paper proves that it is effective to apply Delaunay triangulation to DC resistivity inversion imaging under undulating terrain. |
