For　the　tunnel　crossing　active　fault,　the　damage　induced　by　fault　movement　is　always　serious.　To　solve　such　a　problem,　a　detailed　anti-faulting　tunnel　design　process　for　Urumqi　subway　line　2　was　introduced,　and　seven　three-dimensional　elastic-plastic　finite　element　models　were　established.　The　anti-faulting　design　process　included　three　steps.　First,　the　damage　of　tunnel　lining　from　different　locations　of　fault　rupture　surfaces　was　analyzed.　Then,　the　analysis　of　the　effect　on　tunnel　buried　depth　was　given.　Finally,　the　effect　of　the　disaster　mitigation　method　on　the　flexible　joint　was　verified　and　the　location　of　the　flexible　joint　was　discussed.　The　results　show　that　when　the　properties　of　surrounding　rock　at　the　tunnel　bottom　grows　soft,　the　tunnel　deformation　curve　is　smoother　and　tunnel　damage　induced　by　fault　movement　is　less　serious.　The　vertical　displacement　change　ratio　of　secondary　linings　along　the　tunnel　axis　may　be　the　main　factor　to　cause　shear　damage　to　the　tunnel.　The　interface　between　the　hanging　wall　and　fracture　zone　is　defined　as　the　most　adverse　fault　rupture　surface.　The　tunnel　damage　was　reduced　with　the　decrease　in　the　tunnel　buried　depth　as　more　energy　was　dissipated　by　overburden　soil　and　the　differential　uplift　zone　of　soil　became　more　diffuse.　The　method　of　the　flexible　joint　can　reduce　the　tunnel　damage　significantly　and　the　disaster　mitigation　effect　of　different　locations　on　the　flexible　joint　is　different.　The　tunnel　damage　is　reduced　by　the　greatest　degree　when　the　flexible　joint　is　located　on　the　fault　rupture　surface.　©　2020,　Editorial　Department　of　Journal　of　Southeast　University.　All　right　reserved.
