摘要 Iterative initial value of cable force based on influence matrix and linear programming is determined to study the cable force of long-span concrete-filled steel tube (CFST) arch bridge using the cable-hoisting construction method. Considering the effect of tangential displacement, we observed the appropriate cable force through the golden selection method and iterative forward erection. The cable force determination flow and method aimed at the installation shape are analyzed, which shows that the one-off tension of the cable force on a cable-hoisting CFST arch bridge focusing on installation shape is achieved and serves as a reference for similar engineering practices.

Abstract：Iterative initial value of cable force based on influence matrix and linear programming is determined to study the cable force of long-span concrete-filled steel tube (CFST) arch bridge using the cable-hoisting construction method. Considering the effect of tangential displacement, we observed the appropriate cable force through the golden selection method and iterative forward erection. The cable force determination flow and method aimed at the installation shape are analyzed, which shows that the one-off tension of the cable force on a cable-hoisting CFST arch bridge focusing on installation shape is achieved and serves as a reference for similar engineering practices.
