Influence of confining pressure-dependent Young’s modulus on the convergence of underground excavation

•The relationship between Young's modulus and confining pressure was described as a non-linear function according the test results.•Considering the effect of confining pressure on Young's modulus, the stress and deformation of rock mass around tunnel was calculated by both analytical and n...
