Since it is difficult to measure the displacement and internal stress of a circular tunnel during elliptical deformation in practice, the total original data set comes from finite element analysis
Because it is difficult to measure the displacement and internal stress of circular tunnels during elliptical deformation in practice, the total original data set comes from finite meta-analysis
