Abstract 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.
