The installation of stay cables is an important part of the construction of large-span cable-stayed bridges. Taking the construction and installation of stay cables for the Guanhe Bridge on a high-grade highway near the sea as an example, by analyzing the different traction control conditions of the Guanhe Bridge's stay cable construction, a more optimized suspension plan is obtained. This plan can reduce the difficulty of anchoring and installing the stay cable at the beam end, improve the installation efficiency of the stay cable construction, and ensure safe, high-quality, and efficient construction quality
