The concrete filled steel tube arch bridge that applies cable hoisting cable hanging method to construct is a kind of self-erection structure of precast structure. During the phase of hoisting process, the most pivotal thing is the line form control. By analyzing the influence of system temperature, buckle tower deviation and temporary load on arch on arch rib line form control caused by the inconsistency between actual hoisting temperature and design temperature during the phase of hoisting process; and puts forward the correction method of system temperature difference during the phase of hoisting process. The research shows that controlling and reducing the buckle tower deviation and temporary load on arch can reduce the influence on arch rib line form control during the phase of hoisting process and then enhance the hoisting precision
