This　paper　presents　an　analytical　solution　for　the　stress　and　displacement　for　shallow　twin　tunnels　subjected　to　surcharge　loads.　Multi-interactions,　including　the　interaction　between　liners　and　geomaterial,　the　interaction　between　twin　tunnels,　and　the　interaction　between　surcharge　loads　and　twin　tunnels,　are　considered　in　the　proposed　solution.　The　solution　is　elaborated　using　an　iterative　three-step　procedure　based　on　the　Schwarz　alternating　method.　The　complex　variable　method　and　the　Flamant　solution　and　its　modification　are　employed　in　the　derivation.　Verification　of　the　analytical　solution　is　obtained　through　comparisons　to　a　corresponding　numerical　solution　and　an　existing　case　study.　The　close　correspondence　indicates　the　accuracy　and　generality　of　the　proposed　solution.　A　parametric　investigation　is　performed　to　investigate　the　influence　of　surcharge　load　(including　load　position,　range　and　distribution),　elastic　parameters　of　geomaterial,　and　liner　geometry　(including　tunnel　radius　and　liner　thickness).　Based　on　the　parametric　investigation,　several　advices　for　surcharge　loads　and　liners　are　provided　to　help　tunnel　designers　to　avoid　possible　damages　for　shallow　twin　tunnels.　(c)　2021　Elsevier　Inc.　All　rights　reserved.
