| 摘 要： | 初始地应力场主要由自重场和构造场产生，它是岩土工程设计与施工所要考虑的重要因素之一。根据雪峰山公路隧道实测地应力资料，充分考虑岩体自重与构造应力的影响，采取三维有限元回归分析方法，通过对实测点地应力值用逐步回归分析方法求出回归系数，得到计算区域的初始地应力场。研究成果表明：计算结果与实测值吻合较好，所拟合的初始地应力可作为工程设计与施工的依据。

| Abstract: | In situ stress consists of gravitational and tectonic fields, is one of the most important factors should be considered in design and construction of geotechnical engineering. Based on the field investigation of in-situ stress in Xuefengshan roadway tunnel, in situ stress around the tunnel was regressed simulations. The regression coefficients are obtained from step-by-step regression analysis by 3D numerical The results show that the analysis results are fit well to the field measurements. The regressed in situ stress can be used for sup port design and stability analysis of the tunnel. |
