In　order　to　research　the　influence　on　raft　foundation　of　high-rise　structure　caused　by　the　construction　of　shield　tunnel　underneath,　this　paper　used　the　numerical　simulation　combined　with　onsite　surveying,　and　studied　the　deformation　rules　and　strengthening　measure　caused　by　metro　shield　tunneling　crossing　high-rise　raft　foundation　building.　The　calculation　show　that　when　the　shield　tunnel　excavation　face　away　from　the　monitoring　sites　3D　(D:Shield　tunnel　diameter)distance,　the　raft　foundation　began　to　appear　settlement.　After　3D　spacing　through　monitoring　sites,　the　raft　foundation　settlement　gradually　stabilized;　the　shield　tunnel　excavation　face　away　from　the　monitoring　sites　D　distance,　the　raft　foundation　began　to　appear　tilted.　After　5D　spacing　through　monitoring　sites,　the　raft　foundation　tilt　gradually　stabilized.　Before　advancing　of　the　shield　machine,　grouting　reinforcement　under　the　raft　foundation　can　effectively　reduce　the　incline　of　the　raft　foundation　and　story　drift.　With　the　construction　of　the　tunnel,　the　horizontal　displacement　of　the　high-rise　structure　is　changing　dynamically,　and　the　larger　story　drift　which　occurred　in　the　process　of　construction　should　pay　more　attention.　©　2018,　Editorial　Office　of　Journal　of　Liaoning　Technical　University.　All　right　reserved.
