| 摘 要： | 根据宁南汤家坪流动水准、基线测量出现的重大异常，进行了野外实地考察。发现点位是稳定的；A点与B、C点之间是跨断层的；但原始选点报告所提供的断层产状与作者实测的断层产状有一定的偏差。通过对相关资料分析，认为该场地的地壳形变异常是可靠的。并对其形成机理作了初步探讨。

| Abstract: | A lot of data of mobile observation that include short leveling and short baseline measures crossed the geological fault in the site of Tangjiapin of Ningnan county show some abnormal changes. To check abnormal data and find possible explanation, the field investigation was done. Our work present that the points are stable and the fault is just through between the points of leveling and baseline. But there are some differences about geological structure between our work and before. So the abnormal changes are true. |
