DEFLECTION MEASUREMENT METHOD OF BRIDGE AND DEFLECTION MEASUREMENT DEVICE THEREOF AS WELL AS DEFLECTION MEASUREMENT PROGRAM OF BRIDGE
To provide a deflection measurement method of a bridge and a deflection measurement device thereof as well as a deflection measurement program of the bridge capable of easily measuring deflection of the bridge using an asymmetrical chord offset railroad deflection measured from a vehicle traveling on the bridge.SOLUTION: A deflection measurement method #100 is a method to measure deflection zb of a bridge calculating the deflection zb of the bridge based on measured results of a railroad deflection measurement device measuring 1-2-4 axis asymmetrical chord offset railroad deflection zt,A and 1-3-4 axis asymmetrical chord offset railroad deflection zt,B from a vehicle traveling on the bridge. The vehicle is a two-carriage type measurement vehicle measuring railroad deflection at four axis points from a first axis to a fourth axis in one vehicle. The railroad deflection measurement device measures 1-2-4 axis asymmetrical chord offset railroad deflection zt,A of the second axis and 1-3-4 axis asymmetrical chord offset railroad deflection zt,B of the third axis relating to the first axis and the fourth axis. Deflection calculation processes #130, 140 calculate deflection zb of the bridge based on the 1-2-4 axis asymmetrical chord offset railroad deflection zt,A and the 1-3-4 axis asymmetrical chord offset railroad deflection zt,B.SELECTED DRAWING: Figure 17
