Shield　method　in　subway　construction　may　have　the　influence　or　even　cause　disaster　for　on　adjacent　buildings.　A　section　of　line　No.10　of　Beijing　subway　crossed　through　the　foundation　of　adjacent　buildings.　It＇s　very　important　to　analyze　and　evaluate　the　deformation　of　the　building　in　order　to　protect　them.　So,　based　on　the　detailed　study　of　geological　conditions　and　design　parameters,　FLAC3D　software　combined　with　field　monitoring　data　is　used.　And　then,　research　on　the　effect　and　corresponding　deformation　character　of　adjacent　building　under　construction　of　shield　tunneling　is　presented.　The　result　indicates　that　numerical　simulation　is　close　to　the　monitoring　data,　and　the　effect　caused　by　shield　tunneling　on　the　adjacent　panel　building　is　little　and　the　construction　of　tunnel　is　safe.
