Abstract：Using the nonlinear fitting method based on oval standard equation method, we improves the old method used for obtaining the dip angles of underground steps or fault structure based on quadratic curve equation operated with a least squares way in fitting gzgx gradient space diagram. And then, after comparing groups of experiment calculation of 2D steps and fault dips with different geometrical parameters, the stability and accuracy of the method are verified.
