| 摘 要： | 利用断层滑动资料反演构造应力张量的方法，获得滇西南地区20个构造应力张量数据，并通过与由震源机制解资料求解该地区平均应力场结果的对比，获得了研究区现代构造应力场特征:镇源——营盘山断裂以西至龙陵断裂带以南地区，最大主压应力方向为北北东，应力结构以走滑型为主；龙陵断裂带及其以北的局部地区，最大主压应力方向为近南北或北北西，应力结构为走滑型．

| Abstract: | By means of inversion of fault slip data, the parameters of 20 tectonic stress tensors in southwestern Yunnan region are determined. Compared with the average stress field of the region obtained from focal mechanism solutions, the following characteristics of modern tectonic stress field in this region are obtained. From the west of Zhenyuan Yingpanshan fault to the south of Longling fault zone, the maximum compressional stress is in NNE direction, and the stress regime is mainly of strike slip type. In Longling fault zone and the area north to it, the direction of maximum compressional stress is near NS or NNW, the stress regime is of strike slip type. |
