Damage　to　underground　structures　induced　by　soil　liquefaction　under　cyclic　loads　such　as　earthquakes　has　long　been　an　important　issue　in　underground　engineering　practice.　In　this　paper,　five　models　are　developed　using　Flac3D　software　to　analyze　the　effect　of　burial　depth　on　the　force,　deformation　characteristics,　and　uplift　behavior　of　utility　tunnels　in　the　non-homogeneous　site　containing　a　liquefied　layer.　The　cyclic　shear　property　of　saturated　sand　and　the　increase　in　pore　water　pressure　during　the　earthquake　are　modeled　using　a　cyclic　load-volume　strain　increment　model,　using　Shell-Type　structural　elements　to　model　underground　utility　tunnels,　and　by　using　plastic　hinges　to　represent　the　bending　moment　capacity　of　member＇s　joints.　Numerical　results　show　that　for　shallow-buried　utility　tunnels,　increasing　the　burial　depth　increases　the　bending　moment,　shear　force,　and　deformation　of　the　structure　while　significantly　reducing　its　uplift.　Therefore,　for　high-strength　shallow-buried　utility　tunnels,　appropriate　increase　in　burial　depth　can　improve　its　seismic　safety.
