Technical Advances of Temporary Facilities for the Failure Prevention of Large-Span Cantilever Casting Construction of Mountainous Concrete Box-Type Arch Bridges

Figure 8

Field test of the automatic deviation-rectifying control system in safety control of the west bank cantilever casting construction of the Shatuo Bridge (unit: mm). RI denotes that automatic rectification intervention was initiated. The installation of each box-type segment is composed of four tensioning construction steps, before casting, after casting, before tensioning, and after tensioning, and the designed tension forces were predetermined by the construction design.
