| Abstract: | Based on boundary element method,the physical and mathematical models of upward continuation of plane and curved topography in gravitational field are established.2D and 3D processing softwares are also programmed. The typical 2D and 3D gravitational magnetive anomalies models are processed, and the results and error curves from the typical models are given.The interpretations of data from high-precision gravity survey in Changchunling-Sanzhan region show that the method is feasible and its precision is higher than that of traditional methods. |
