Abstract EN
Finite element method is an important method to solve mathematical problems in engineering.
Many mathematical equations are difficult to solve, but it becomes very simple after using the finite element method.
In this paper, the finite element method is applied to the calculation of gravity anomaly.
First, the variational equation of gravity anomaly calculation is established, and then the gravity anomaly value ten times the distance away from the anomaly body is used as the boundary condition.
By comparing the gravity anomaly obtained by solving the stiffness matrix with the analytical solution, it can be found that the method in this paper has high accuracy.
Finally, the model of Jinchuan copper nickel deposit is used for calculation, and the calculated gravity anomaly field is inverted with Growth3D.
It can be found that the inversion result is very close to the model, which verifies the effectiveness of the algorithm in this paper.
