Abstract
Based on a hybrid composite girder cable-stayed bridge, a finite element model was established to analyze the technical parameters such as the cable force, the weight of the main beam, and the cantilever length of the hanging basket crossing the auxiliary pier. The construction accuracy and construction control standard of cable force and main beam weight were discussed, and the maximum cantilever length of hanging basket crossing temporary and permanent auxiliary piers was demonstrated. The results show that the construction accuracy of the overstretched cable force of the medium-span cable-stayed cable should be controlled within 5%; the under-stretched cable force of the medium-span cable-stayed cable should be controlled within 1.5%, and the final cable force adjustment of a cable-stayed bridge should be controlled within 1%. The construction accuracy of concrete beam weight should be controlled within 3%, or in other words, the average error of concrete slab thickness should be controlled within 1 cm, and the weight of the composite beam should be controlled within 0.6%. The maximum cantilever length of the hanging basket crossing the temporary auxiliary pier can be two beam sections during construction, and the maximum cantilever length of the hanging basket crossing the permanent auxiliary pier can be four beam sections. In the process of construction control, alignment control should be the focus, with cable force control as the supplement.
