| 中文摘要:本文在实测现今构造应力场分析的基础上，运用有限元数值模拟方法对黄河李家峡水电工程坝区及外围现今构造应力场作了进一步分析：认为李家峡水电工程坝基岩体在完整岩体条件下是稳定的；并且，坝前Ⅰ、Ⅱ号滑坡在天然状态下整体是稳定的。 |

| Abstract: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. |
