Study on Diagnosis and Treatment Technology of Cracks in Consolidated Continuous Box Girders of Middle Piers during Construction

In this paper, taking the cast-in-place reinforced concrete continuous box girders of a bridge as research object, we studied cracking type and their construction. Combined with calculation analysis construction, causes effects cracks during construction were further studied. Then maintenance strengthening scheme that UT10 super-highperformance should be used on floor was proposed, which will provide reference for diagnosis treatment similar structures.
