| Abstract: | Single-column-pier bridge has been widely used in urban interchanges and viaducts as its simple structural form and small sites. However, the stability of single-column-pier bridges has attracted more and more attentions due to many overturning collapse accidents occurred in recent years. This paper provides optimized anti-overturning and reinforcement design solution for single-column-pier bridges based on scheme selection for various bridge types and engineering practices in Nanjing.Keywords: Single-column-pier bridge; Anti-pull device; Anti-overturning stability coefficient |
