| 摘 要： | 断层活动性评价是研究区域构造稳定性的基础,它直接影响到水工建筑物本身的抗震安全。目前,对于断层活动性评价较常用的方法就是有关断层样品的年龄测试,这是比较直观的定量方法之一。但由于测年方法有多种,同一样品用不同的测年方法测得的结果有时偏差很大,哪种结果更为可靠始终是众多学者所关心的问题。本文对在水利水电工程断层活动性评价中关于断层年龄引用方面存在的一些问题进行探讨,并结合溪洛渡工程对研究区的马边盐津断裂、莲峰断裂和金阳断裂进行了断裂活动性分析与评价。

| Abstract: | The faults activity appraisal is a foundation for study of regional tectonic stability because it directly affects the safety of a hydraulic engineering structure against seismic activity.Dating of fault gouge is now a common method for evaluation of faults activity,one of the quantitative methods.However,different dating methods tend to give different results even for the same fault gouge sample,which has caused concerns on the reliability of fault activity appraisal.In this paper,the author discusses some of problems in adduction of dating information of the fault gouge in hydropower projects and suggests methods for resolving the problems.A case study on the activity of Mabian-Yanjin,Lianfeng and Jinyang faults of the Xiluodu hydroelectric project is presented to demonstrate methods suggested by the author. |
