been put on the track.
4) The girder web s vertical deflection b≤H/ 500 (as shown in Figure 4 1 10-4).
It shall be measured at the long ribbed slab.
5) The bridge frame diagonal difference | D 1 D 2 | ≤5mm ( as shown in Figure
-
4 1 10-1).
6) The waviness of the girder main webplate, which is checked by a 1m leveling rul⁃
er, shall be no larger than 0 7δ within a distance of 1/ 3H from the upper cover
plate and no larger than 1 0δ at other locations (as shown in Figure 4 1 10-5).

7) The degree of verticality of the support leg in the span direction h 1 ≤H/ 2000
(Figure 4 1 10-6) and the direction of tilt shall be symmetrical with each other.
