| Abstract: | The authors describe in their paper the design of the pre-camber of the 75-m long continuous box girders, the geometric linear technique to control the precision of precasting of segments of the box girders and the collection and control of geometric data. The authors also illustrate the setting of the precasting segments, arrangement of geometric reference points and the guiding principle for controlling the allowable error in surveys as well as the methods for compensation and correction of error during the prefabrication of the box girders. |
