【摘要】 重力梯度张量(GGT)矩阵的特征向量与场源体的位置、走向等有关.笔者在前人工作的基础上,对利用GGT定位场源体中心及推断走向的方法进行了研究.文中采用滑动窗口,按不同的异常下限,确定一系列Gzz极值点作为计算点.随后依据距离指标,采用变窗口最小二乘中心定位方法进行了计算.当计算点趋近二维构造时,最小特征值对应的特征向量可以大致推断目标体在该测点处的走向.理论模型数据实验表明,本方法反演结果较为准确,效果明显.更多还原

【Abstract】 The eigenvectors of the gravity gradient tensor are related to the center of mass and its strike direction. On the basis of previous work,the author uses GGT to locate the geologic bodies and infer their strike directions. According to the different threshold,using a sliding window to determine a series of extreme points as calculation points. When the calculating points reaching a two-dimensional structure, the smallest eigenvalues and the corresponding eigenvectors can infer the strike direction. Theoretical model test shows that this method is reliable,and hence its effect is obvious.更多还原
