摘要
将粒子群算法与位错理论模型相结合,利用青藏高原东北缘2001—2004年的GPS观测数据,对祁连山断层的三维滑动速率进行反演计算。结果表明,粒子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获得的结果具有较好的一致性。
Using the particle swarm optimization algorithm combined with the dislocation model, we inversed three-dimension slip velocity of the Qilian mountain fault from GPS data observed in north-east margin of the Qinghal-Tibet Plateau during 2001-2004. The results show that the particle swarm optimization algorithm can used for computing three dimension slip velocity of the fault effectively, and the results have the good consistency with those obtained by geological methods.
