The　absence　of　a　material　characteristic　length　in　local　strain　softening　models　often　leads　to　mesh　dependency　issues　in　structural　failure　simulations,　significantly　compromising　the　accuracy　and　reliability　of　calculation　results.　A　nonlocal　Hoek-Brown　softening　plasticity　model　was　proposed　in　this　study.　This　model　utilized　a　smooth　Hoek-Brown　strength　criterion　to　construct　the　yield　function　and　transformed　the　equivalent　plastic　shear　strain　into　the　nonlocal　variable　using　a　nonlocal　integral　formulation,　effectively　mitigating　mesh　dependency　issues　in　structural　failure　simulations.　The　im⁃　plicit　return　mapping　algorithm　was　adopted　to　solve　the　differential　equations　of　the　nonlocal　plasticity　model,　and　the　finite　element　implementation　process　of　the　model　was　detailed.　Finally,　the　validity　of　the　model　was　verified　through　two　classic　examples:　the　compression　failure　of　an　imperfect　plate　and　the　bearing　capacity　problem　of　a　strip　foundation.　The　results　showed　that　during　mesh　refine⁃　ment,　the　simulation　results　of　the　nonlocal　Hoek-Brown　softening　plasticity　model　were　insensitive　to　mesh　size.　The　predicted　shear　band　width　and　load-displacement　curves　remained　largely　unaffected　by　changes　in　mesh　size.　The　proposed　model　can　provide　a　calculation　tool　with　mesh　objectivity　for　failure　analysis　in　rock　engineering.　©　2025　Editorial　Office　of　Journal　of　Disaster　Prevention　and　Mitigation　Engineering.　All　rights　reserved.
