| 摘 要： | 雪峰山隧道为深埋隧道，初始地应力场对围岩变形特性具有重要的控制作用。运用水压致裂法测试、室内Kaiser效应测试和有限元数值模拟等3种方法，对雪峰山隧道初始地应力场进行了研究，并对雪峰山隧道的初始地应力场作出了较准确的判断，为隧道的设计与施工提供了可靠的依据。对3种方法进行了对比分析。

| Abstract: | The Xuefeng mountain tunnel is the largest controlling project of ShaoHuai express highway. The initial geostress field have an important influence to deformation of surrounding rock. In the paper, making use of local testing in hydrofracturing, indoor testing of Kaiser effect of rock and finite element numeric simulation, the geostress status of the Xuefeng mountain express highway tunnel is studied, we has made a accurate judgement to the Initial geostress field in The XueFeng Mountain Tunnel. The study has supplied basis for the tunnel design and construction. In the paper, the three methods are compared. |
