| 摘 要： | 地应力作为工程建设的基础地质条件之一，已得到较高重视，许多大型工程都开展了地应力的测试分析研究。本文选取两种典型的深切峡谷，运用三维有限元软件模拟河流下切、河谷形成过程，得到了现今的峡谷应力场。在此基础上，详细分析各自应力场的空间分布特征，并将两者进行了对比分析。得出高山峡谷应力场分布的一般规律。

| Abstract: | The importance of geo-stress study is recognized gradually, and the geostress tests and analysis are carried out without exception in big projects, especially hydro-electric projects. In this paper, taking two typical deep-cutting gorges as examples, the development procedures of the gorges are simulated using three dimensional elastic finite element method package, and the present geo-stress fields are obtained. Then the spatial distribution characteristics of the geo-stress fields are analyzed and compared in detail. At last the common distributing rules of geo-stress in deep-cutting gorge are discussed. |
