Tunnel　monitoring　measurement　is　an　important　working　procedure　of　the　tunnel　construction,　and　it　is　also　one　of　the　three　elements　of　＂new　Austrian　method＂.　Currently,　most　of　the　data　is　stored　and　processed　by　EXCEL,　however,　due　to　the　large　amount　of　tunnel　monitoring　measurement　task,　the　amount　of　data　that　had　been　collected　from　the　scene　is　very　huge　every　day,　therefore,　just　relying　on　technicians　manually　to　input,　store,　classified　process　data　and　generate　reports　which　will　take　up　a　lot　of　manpower　and　material　resources,　and　very　easy　to　make　mistakes　in　the　meantime.　Because　of　the　lack　of　practical　and　efficient　monitoring　data　analysis　and　processing　technology,　monitoring　work　is　difficult　to　play　a　real　role.　This　paper　which　based　on　Access　of　Microsoft　has　developed　an　automatic　warning　system　of　tunnel　monitoring　that　has　a　friendly　user　interface.　This　system　contains　lots　of　functions,　such　as　data　inputting,　storage,　inquiring,　alarm,　and　regression　analysis,　what＇s　more,　it　also　effectively　improves　the　efficiency　and　management　level.
