| 摘要: |
| A Study of Present Tectonic Stress Field in and around the Damsite of the Lijiaxia Hydropower Project on the Yellow River |
| On the basis of field measurements such as in-situ fault displacement measurement ,crustalde-formation ,focal mechanism solution and stress measurement etc.,this paper gives a further analy-sis of the present tectonic stress field in the given region by the method of finite element numericalsimulation, Boch in-situ measured and simulated results show that the rock body of the dam founda-tion of the Lijiaxia hydropower station ,as a whole ,is stable ,and the whole Ⅰ and Ⅱ landslides infront of the dam are stable in natural state. |
