摘要
应用弹塑性小应变大变形理论,运用三维有限元方法研究了台湾软岩隧道在高地应力和围岩岩体力学参数较低的情况下,围岩变形、受力及破坏状态与开挖方式和支护方案的关系,得到了一些有益的结论,为该地区隧道合理施工提供了依据。
The relationships among deformation, stress and damaged state of surrounding rock mass of soft rock tunnel, excavation methods and supporting schemes are studied under the conditions of high geostress and low mechanical parameters of rock mass based on small strain-large deformation theory and 3D FEM. Some useful results are obtained and can be used as theoretic basis for the reasonable construction of tunnel in special area.
