根据河西地区2002-2003年和2004-2005年的重力观测资料,用蚁群算法反演皇城一塔尔庄断层的运动。反演结果表明:蚁群算法可以有效地求解断层的三维滑动速率,计算结果与用地质等方法得到的结果基本吻合。反演结果显示皇城、塔尔庄断层的滑动速率呈空间不均匀性分布特征。
On the basis of the gravity change data of the Hexi area in 2002 to 2003 and 2004 to 2005 years, the movements of the Huangcheng-Taerzhuang fault were inverted by use of the ant colony algorithm (ACA). The inversion result shows that the ACA can be used for solving the 3D slipe rate of a fault effeciently,and the result is in basical accordance with the result obtained with geological method. Moreover, the result shows that the slipe rate of the Huangcheng-Taerzhuang fault appears spatially unevenness.
