There have been many studies on the elastic–plastic problems of circular tunnels in the past, especially for axisymmetric problems, which have been extensively researched. For the non-axisymmetric problems with non-hydrostatic stresses, the author discussed the distribution of the plastic zone around the circular tunnel using analytical methods.

摘要

There have been many studies on the elastic–plastic problems of circular tunnels in the past, especially for axisymmetric problems, which have been extensively researched. For the non-axisymmetric problems with non-hydrostatic stresses, the author discussed the distribution of the plastic zone around the circular tunnel using analytical methods.
