摘要
提出把棱柱体单元的重力正演计算方法与遗传算法相结合,进行三维密度结构反演。介绍了目标函数的构建及遗传算法过程,通过模型试算证明了该方法的有效性和稳定性,并利用该方法反演了青藏高原东缘三维密度分布。
A new inversion method for 3D density structure is proposed, which combines the method of gravity forward of 3D rectangular prism with genetic algorithm, the approach of constructing the objective function and the procedure of genetic algorithm are introduced. The validity and stability of this method are proved by synthetic data. With this method the three-dimensional distribution of density in eastern Qinghai-Tibet plateau is inverted from Bouguer gravity anomaly.
