| Abstract: | Taking waste Yellow river Bridge at the Huai'an in the Beijing-Shanghai highway as an example,the paper studies the jack-up scheme for multi-span bridge girder in the bearing replacement of the continuous girder bridges and points out to adopt the electric resistance-strain method to inspect the increasing number of the strain of the girders in the test of jack-up, and it also proves the feasibility of the construction scheme. |

| Keywords: | continuous girder bridge support jack-up electric resistance method |
