| 摘 要： | 针对传统顺序联合反演的缺陷,通过改变地下空间的网格剖分方式和约束条件的约束方式来进行相应的改进,并将拟BP神经网络算法和小波多尺度分析应用到反演中,以提高反演结果的分辨率和收敛速度。龙门山地区遂宁-阿坝剖面的反演结果表明,本文方法具有更好的反演效果。

| Abstract: | 〗Although the sequence joint inversion is a priority method of joint inversion with gravity and seismic data, its theoretical basis is less comprehensive than the theoretical basis of synchronous joint inversion. So, we analyze the weak points of the sequence joint inversion, and make some improvements in the mesh mode of geological structure and constraints. Then we employ wavelet multi-scale analysis and quasi-BP neural network inversion to improve the resolution of the result and to accelerate convergence. The inversion of Suining-Aba in the Longman mountains shows that the inversion effect of this method is obvious. |
