AbstractBecause of the high-pier and basket cantilever constructionthe construction of long-span continuous rigid frame bridge with high piers has large security risks. From the construction process of the long-span continuous rigid frame bridge with high piersbased on the analysis of the factors affecting the safe constructionsafety precautions are proposedwhich provide references for the safety of similar bridge construction.
