本文提出了应用两层二度矩形棱柱体的下界面近似地模拟两个密度界面起伏的重力反演法。以棱柱体的参量作为未知数,重力异常作为常数项,以此建立一个矛盾方程组。此方程组的解,即为所求的密度界面的起伏变化。该方法可用于同时求取康腊面和莫霍面。方法具有一定的精度,在理论模型上的试验取得了较好的效果。
In this paper, we propose a gravity inversion method that simulates the undulation of two density interfaces by using the lower interface of two second-order rectangular prisms. Taking the parameters of the prism as the unknown and the gravity anomaly as the constant term, a contradictory equation set is established. The solution to this system of equations is the change in the density of the desired interface. This method can be used for simultaneous determination of both the Kahlan and Moho surfaces. The method has a certain accuracy, and the experiment on the theoretical model has achieved good results.
