In　order　to　carry　out　mechanical　analysis　of　continuous　beams,　the　transfer　matrix　method　improved　from　the　matrix　displacement　method　was　presented.　Finite　element　method　was　employed　to　discretize　the　continuous　beams　so　as　to　obtain　the　displacement　vector,　force　vector　and　cell　rigidity　matrix.　Transfer　matrix　method　was　employed　to　determine　the　transfer　relation　of　the　poles　in　the　beam.　The　displacements　and　inner　forces　at　crunodes　can　be　solved　based　on　given　boundary　conditions.　A　practical　calculation　project　of　the　continouous　beams　was　demonstrated　which　can　verify　the　validity　of　the　presented　method.　This　method　can　simplify　the　calculation　greatly　and　is　more　suitable　for　the　inner　force　calculation　of　continuous　beams　by　using　computer.
