| Abstract: | Taking cable tongs stakingout of the Fourth Nanjing Yangtze River Bridge as the case, it presents the basic method and process of the calculation of cable tongs position and the stakingout. Analysis is made on the factors that affect the accuracy of suspension bridge cable tongs and the countermeasures. Practice has proved that the method of cable tongs lofting is simple, reliable, and complies with the design require- ments. |
