摘要
利用改进的蚁群算法并结合位错理论模型,以及青藏高原东北缘1999—2001年期间的GPS数据,对祁连山断层的三维滑动速率进行了反演。结果表明,蚁群算法可有效地求解断层的三维滑动速率,其反演结果与地质等方法的结果具有较好的一致性。
The ant colony algorithm is modified by replacing tour length and visibility based on the characteristics of fault parameters, and combined with the theoretical dislocation model, using the GPS observations in the north-east edge of the Qinghai-Tibet plateau during 1999--2001, the Qilian fault 3D slip rates are inversed. The results show that the ant colony algorithm is effective for solving the problem of inversion of 3 D fault slip rate parameters, the results of the numerical inversion has the good consistency with those of geological methods.
