  • To investigate a method of setting working platforms during the concrete pouring for the main arch ring of a rigid skeleton under a reasonable stress and with a convenient and economical construction and taking the Nanpanjiang Super Long Span Bridge as an object, the transient stress variation process of rigid skeleton caused by the first ring concrete symmetrically poured from the two arch springs was analyzed. The stress process curves of the main control section of rigid skeleton were obtained. A concrete pouring method for the main arch ring was proposed with four working platforms arranged symmetrically along the longitudinal arch, and the working platforms were set at the arch spring section and the peak of control stress process curve, such that the stress increments on the rigid skeleton generated by the cocrete of two working platforms within the half span had different signs to offest part of the stress. By fitting the continuous functions of the ascending and descending sections of absolute control stress process curve, the pouring length and sequence of concrete was reasonably adjusted to reduce the transient stress and deformation of rigid skeleton. The construction operability and economy of the four-working-platform method were discussed, and the stress and deformation of rigid skeleton during the concrete pouring process for the first ring of main arch ring of Nanpanjiang Super Long Span Bridge were analyzed. Research result shows that the stress process curve of concrete filled in the arch spring tube represents a control stress and single wave curve. The proposed four-working-platform method with the order of first along the span, then in arch spring and with the length calculated by the fitting function is reasonable for the concrete pouring of Nanpanjiang Super Long Span Bridge. The maximum transient tensile and compressive stresses of rigid skeleton reduce to 0.4 and 23.5 MPa, respectively, which are well controlled within the range of material strength. The vault has no upward deflection, the maximum transient deflection and eternal ring deflection are 192 and 82 mm, respectively, and the arch axis does not deform repeatedly. The four-working-platform pouring method requires less equipment and personnel, is economical, and has good operability. It is suitable for the concrete pouring for the main arch ring of rigid skeleton arch bridges, and can be used for similar bridges.
