In　this　study,　the　author　has　developed　a　data　management　system　of　tunnel　monitoring　by　using　ACCESS　database　and　made　a　new　exploration　in　the　field　of　tunnel　monitoring　data　management.　This　study　introduces　the　principles,　the　methods　and　the　functions　of　this　system.　The　system　sets　data　input,　data　management,　data　applications　and　other　functions　all　in　one.　It　has　made　a　good　connection　between　the　visual　interface　of　front　deskand　the　ACCESS　database　for　monitoring　information　storage.　What＇s　more,　it　has　realized　functions　of　data　entering,　storage,　querying,　generating　tense　curve　and　space　state　diagrams,　regression　analysis　and　reports　generating.　The　successful　application　in　the　engineering　practice　proves　the　validity　and　reliability　of　this　system　and　it　also　providesanew　way　for　tunnel　monitoring　data　analysis.　©　Maxwell　Scientific　Organization,　2013.
