Seven　commonly　used　calculation　methods　for　surrounding　rock　pressure　were　selected　to　analyze　the　influences　of　tunnel　buried　depth　and　tunnel　width　on　the　calculation　results　of　surrounding　rock　pressure.　The　advantages,　disadvantages　and　application　scopes　of　these　calculation　methods　were　analyzed　and　compared.　The　results　show　that　the　whole　soil　column　theory　is　applicable　to　the　open　cut　backfill　engineering　regardless　of　tunnel　width,　tunnel　engineering　with　shallow　buried　depth　and　poor　surrounding　rock　conditions.　Przewalski＇s　formula　is　applicable　to　deep　buried　tunnels　with　definite　self　bearing　capacity.　＇　Code　for　Design　of　Artificial　Rock　Cavern＇　and　＇　Specification　for　Design　of　Hydraulic　Tunnel＇　are　applicable　to　tunnels　with　better　surrounding　rock　conditions　and　regardless　of　the　tunnel　width.　Terzaghi　formula　and　Bill　Bauman　formula　are　applicable　to　shallow　buried　tunnels　with　poor　surrounding　rock　conditions.　The　calculation　method　for　surrounding　rock　pressure　in　＇　Code　for　Design　of　Railway　Tunnel＇　has　integrated　the　advantages　of　the　whole　soil　column　theory,　Xie　Jiaxiao　formula　and　the　empirical　formulas　based　on　sample　statistics　and　surrounding　rock　classification.　It　has　a　relatively　well-defined　physical　concept,　and　is　easy　to　use　for　engineers　and　technicians.　However,　the　empirical　formulas　couldn＇t　give　a　continuous　solution　to　surrounding　rock　pressure　with　the　change　of　buried　depth,　and　it　is　suggested　to　be　further　modified　and　improved　by　combining　with　theoretical　analysis.
