| Abstract: | Authors use the finite element method to analyze and study stress and deformation of the support structure of a soft adjacent rock tunnel which is built with polypropylene fiber mesh wet_spray concrete, anchor rod and steel grids. The calculation of the strength of dangerous sections testifies that the railway tunnel with this support structure has high stability and safety. |
