Creeping Mechanism Analysis of Curved Bridges

Creeping diseases can reduce driving comfort and endanger structural safety, so it is necessary to analyze the causes of creeping. Based on existing research, the factors of the creeping phenomenon using TianNingSi overpass as an example related to the features of radial displacement under dead load, live load, concrete shrinkage and creep, temperature, prestress, etc., were analyzed. The study shows that centrifugal force is the main cause of creeping in curved bridges, which have heavy traffic and large curvature radii. The deficiencies in infrastructure and bearing form should be the main cause of creeping disease. Bearing form optimization can prevent creeping diseases.
