The invention discloses a large-span stiff skeleton
arch bridge skewback foundation
mass concrete crack control method, and relates to the technical field of
bridge engineering, and the
system comprises the following components: S1, building a collaborative analysis model, S2, analyzing deformation influence, and S3, implementing crack control measures. The method has high pertinence and practicability by adjusting the concrete
mix proportion, adding the admixture, setting
temperature control measures and optimizing the reinforcement design, the concrete
mix proportion and the
cement dosage can be adjusted in a targeted mode through the concrete
stress distribution condition and the stiff skeleton deformation condition obtained through the collaborative analysis model, and the construction efficiency is improved. The additive is added to reduce the
adverse effect of hydration heat, meanwhile,
effective temperature control measures are set according to the temperature field distribution condition, in addition, by optimizing the reinforcement design, the
bearing capacity and
crack resistance of the skewback foundation can be further improved, the crack risk of large-size concrete of the skewback foundation of the large-span stiff skeleton
arch bridge is effectively reduced, and the service life of the large-span stiff skeleton
arch bridge is prolonged. And the overall quality and safety of a project are improved.
