| 摘 要： | 结合地质、地球物理和小震精定位结果,对小江断裂带3条断层参数地质分段进行合理选取,并设定一定的差异范围,利用GPS区域网资料分析各断层段的变形状态.结果表明,断层参数的设定对反演结果影响很大(导致断层的位错量差异高达3 mm).在断层参数难以确定的情况下,扫描线段法在一定程度上能反映断层的变形状态.

| Abstract: | From the results combined with geology,geophysics and fine positioning of small earthquakes,the fault segment parameters were selected reasonably and the a certain scope of differences in Xiaojiang fault segments was set, and the deformation of fault segments was analyzed using GPS data.The analyzing results show that the fault parameters have relatively big impact on the inversion results,and the calculated dislocation difference is up to 3mm.In the case of difficultly defining fault parameters,the process... |
