description The invention discloses a prestressed concrete continuous beam dismantling method, and relates to the technical field of bridge engineering. The method comprises the steps of S1 constructing a side span support, and enabling the side span support to support side spans on two sides of a continuous beam; S2 removing and transferring a mid-span closure segment; S3 removing and transferring a side span closure segment; S4 removing and transferring side span beam segments between the side span closure segment and side piers; and S5 using the side span support as a supporting structure, and sequentially and alternately removing and transferring the remaining side span beam segments and the remaining mid-span beam segments between the side span closure segment and the mid-span closure segment till all the segments of the continuous beam are dismantled. According to the method, the side span support is constructed, the mid-span closure segment and the side span closure segment are dismantled in sequence, and then the
