昆明盆地活断层风险评价

The Active Fault Investigation of Kunming Basin

摘要: 活断层研究是区域地壳稳定性研究的重要方面，对于城市建设场地稳定性、城市地震防灾减灾、城市建筑物地震烈度设防等方面具有重要意义。本文通过对历史文献和前人研究成果的收集、整理，结合野外地质调查结果和航、卫影像的线性结构特征，对昆明盆地普渡河–西山断裂、黑龙潭–官渡断裂、白邑–横冲断裂、大春河–一朵云断裂、富民–呈贡断裂五条活断层活动性进行调查，并分析活断层对昆明市城市规划建设的影响。

Abstract: Active fault research is an important aspect of regional crustal stability studies. It is a great signi-ficance for site stability of urban construction, prevention of urban earthquake disaster and seismic intensity fortification of city building. By collecting historical documents and previous research achievements, combining with the field geological survey and linear structure characteristics of satellite image, we make a survey of the main active faults (such as Puduhe-Xishan, Hei-longtan-Guandu fault, Baiyi-Hengchong fault, Dachunhe-Yiduoyun fault, Fumin-Chenggong fault) in Kunming basin, and analyze the influence of active fault on city planning and construction.
