Abstract：

Considering　a　horse-shaped　deep　tunnel　subjected　to　far-field　stresses　and　lining　inner　pressure,　a　complex　variable　solution　is　presented　in　this　paper　to　describe　the　stress　and　displacement　distribution　around　the　surrounding　rock　mass.　The　solution　is　implemented　in　the　platform　of　MATLAB　and　then　verified　by　numerical　simulation　in　the　platform　of　FLAC3D.　In　addition,　the　influences　of　far-field　stresses　and　lining　inner　pressure　on　the　stress　and　convergence　along　tunnel　perimeter　are　discussed　through　case　study.　©　2014　American　Society　of　Civil　Engineers.
