摘要
为提高桥梁工程的设计水平,文章总结了独柱墩桥梁的受力特点及典型破坏模式,依托某曲线型独柱墩桥梁,利用Midas Civil软件计算了其在不同曲率半径和支座间距下的抗倾覆安全系数,并从单点支撑改多点支撑、上部结构压重两方面阐述了独柱墩桥梁的加固措施,旨在为独柱墩桥梁设计提供理论参考。
In order to improve the design level of bridge engineering,this paper summarizes the stress characteristics and typical failure modes of single column pier bridge.Based on a curved single column pier bridge,Midas Civil software is used to calculate the anti-overturning safety factor under different curvature radius and support spacing.The reinforcement measures of single column pier bridge are expounded from two aspects of changing single-point support to multi-point support and upper structure weight,aiming to provide theoretical reference for the design of single column pier bridge.
