Before　the　construction　of　Metro　station,　many　accessory　structures　need　to　be　constructed　firstly,　including　shaft,　Cross　channel,　and　metro　station　pilot　tunnel,　etc.　Many　Engineering　cases　show　that　the　risks　of　the　circumstances　around　the　Metro　station　caused　by　the　excavation　of　these　accessory　structures　are　the　major　component　of　the　metro　construction　risk.　In　this　paper,　the　risk　caused　by　construction　of　the　metro　shaft　adjacent　to　building　was　studied,　which　located　at　the　crossings　of　ziyou　Road　and　Renmin　Street,　Changchun,　China.　Firstly,　the　major　risk　was　introduced　and　the　construction　mechanic　behavior　was　researched　by　using　MIDAS/GTS　finite　element　software　package.　Then,　a　control　method　was　proposed　to　eliminate　this　risk,　which　was　verified　by　using　finite　element　software.　Finally,　the　proposed　measure　was　also　validated　with　the　result　of　construction　monitoring　for　this　project.　This　works　focus　on　studying　the　excavation　mechanics　behavior　of　metro　shaft　and　its　influence　on　the　around　environment,　and　these　conclusions　are　useful　for　providing　a　basis　for　similar　project　construction　in　the　future.　(C)　2016　Published　by　Elsevier　Ltd.
