Abstract：
Considering that the measured ring prestress tensioning elongation of anchorage area of Songyuan Bridge cable-stayed tower is bigger than the theoretical elongation, this paper analyzed the factors influencing large-curvature ring prestress tensioning elongation, proposed the correction method for calculation of large-curvature ring prestress tensioning elongation and studied the control method for large-curvature ring prestress tensioning.
