Analytic　solutions　for　stress　and　displacement　of　twin　tunneling　at　great　depth　considering　liner　installation　and　mutual　interaction　between　geomaterial　and　liners　are　the　key　context　in　this　paper.　Twin　tunneling　is　a　continuous　procedure,　in　which　after　one　tunnel　is　excavated　and　lined,　the　other　one　is　hysteretically　excavated　and　lined.　The　presented　solutions　mainly　focus　on　stress　and　displacement　in　geomaterial　and　liners　for　the　hysteretical　phases　through　an　iterative　combination　of　the　complex　variable　method　and　the　Fourier　transform　via　the　Schwarz　alternating　method.　The　presented　solutions　are　verified　by　comparing　to　a　corresponding　numerical　solution　of　a　general　case,　in　which　a　good　agreement　is　observed　after　three　iterations.　Subsequently,　a　dimensionless　parametric　investigation　is　performed　to　investigate　the　influence　of　tunnel　geometry　(including　twin　tunnel　spacing,　relative　angle　of　twin　tunnels　and　relative　size　of　twin　tunnels),　liner　properties　(including　liner　thickness　and　liner　installation),　and　lateral　stress　coefficient　on　stress　and　displacement　in　both　liners　and　geomaterial.　©　2019　Elsevier　Inc.
