摘要
以南京长江第四大桥索夹放样为例,介绍该桥索夹位置计算和测量放样的基本方法和流程。分析影响悬索桥索夹放样精度的因素,并加以修正或消除,用以提高索夹放样精度。实践证明本桥索夹放样方法简单、可靠,满足设计要求。
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.
