Abstract:
The structure characteristics of cable-stayed and anchored cantilever casting construction system for the main arch ring of arch bridge were analyzed. The methods to determine the forces of anchored cables in cantilever casting construction were summarized. The advantages, disadvantages, and applicabilities of the zero displacement method, the fixed length jacking cable method, the influence matrix method, and the zero moment method were analyzed. The design and construction schemes of Matihe Bridge being a reinforced concrete arch bridge with net-span of 180 m was taken as engineering background, and the main construction process of long span arch bridge built by using cable stayed cantilever casting method was analyzed. The cable forces were calculated by using the zero moment method, the cable forces at the maximum cantilever construction stage were optimized by using the influence matrix method with the objective function of bending strain energy. Analysis result shows that the zero moment method is determined to be the most direct and effective control method for the cable-stayed and anchored cantilever casting construction of arch bridges. The stresses in the arch ring section change gradually from partially tensile state to completely compressive state, and both the alignment and stress of arch ring satisfy the design requirements in whole construction process. The tensile stresses of arch ring at the top and bottom sides do not exceed 1.5 MPa, the compressive stresses are no more than 7.0 MPa, and the displacements of arch ring are no more than 10 mm. As the cable forces at the maximum cantilever construction stage are optimized, the alignment of arch ring can be adjusted, and its stress state is improved, thus the stress state of arch foot can be closed to “zero” state. The stability of arch ring at cantilever casting construction stage is closely related to the stayed and anchored cable system, and the internal forces, alignment, and stability during construction process are simultaneously dominated by a reasonable stayed and anchored cable system. The stress of arch ring is deeply influenced by the different removal procedures of stayed and anchored cable system, thus the removal process of stayed and anchored cable system should be optimized during construction process. The research results have been successfully applied to the design of the construction scheme and construction control of cantilever casting of the longest span reinforced concrete arch bridge in China, and can be taken as a reference for the design and construction control of other long span arch bridges, which has a practical significance in promoting the development and application of cantilever casting technology of long span reinforced concrete arch bridges. 2 tabs, 10 figs, 29 refs.
