In　order　to　explore　the　surrounding　rock　disturbance　in　the　shallow　buried　double-sided　biased　small　clear　distance　tunneling　process,　relying　on　a　national　highway　project,　the　finite　element　Midas　Gts　Nx　was　used　to　conduct　numerical　simulation　analysis　of　the　tunnel　construction　process,　in　order　to　analyse　the　law　of　surrounding　rock　stress　and　strain　in　the　shallow　buried　double-sided　biased　small　clear　distance　tunneling　process.　The　results　show　that　the　subsidence　shape　of　surface　slope　develops　from　＇V＇　shape　to　＇W＇　shape,　and　the　vertical　horizontal　displacement　shape　of　septal　rock　changes　from　＇V＇　shape　to　＇W＇　shape.　The　surrounding　rock　produced　a　certain　amount　of　uplift　halfway　up　the　mountain.　When　the　rear　tunnel　is　driven,　the　centre　of　gravity　of　the　septum　rocks　migrates　towards　the　rear　tunnel　side,　which　reduces　the　stress　of　the　surrounding　rock　at　the　front　tunnel　and　is　conducive　to　the　stability　of　the　front　tunnel　structure.　The　stress　increase　of　the　middle　barrier　rock　at　the　arch　foot　is　obvious　and　it　has　the　characteristic　of　through-through.　The　stress　of　the　structure　at　the　tunnel　wall　foot　should　be　monitored　emphatically　during　construction.　When　the　rear　tunnel　is　driven,　the　plastic　zone　of　surrounding　rock　appears　on　the　diagonal　of　the　septum　rock,　and　the　safety　factor　of　surrounding　rock　is　increased　and　the　speed　is　reduced.　Numerical　simulation　can　provide　theoretical　guidance　for　field　monitoring　and　measurement.　©　2023　The　Authors.
