近几年，独柱墩桥梁越来越多应用于高速公路匝道桥梁和市政立交桥梁，在车辆超载和偏载的不利工况下，独柱墩桥梁发生倾覆倒塌的事故时有发生。在调研浙江省内大量具体工程的基础上，对独柱墩桥梁的结构受力特点进行分析，并根据受力特点和病害情况提出几种有针对性的加固设计方案，可供同类桥梁设计和加固维修参考。

In recent years ,more and more bridges supported by single -column piers were applied to the ramp's bridges of expressway and municipal flyovers. Under the bad working condition of the vehicle overloading and partial load ,the bridges supported by single -column piers usually collapsed or capsized.Based on the investigation of a lot of engineering in Zhejiang province ,the structure characteristics of the bridges supported by single -column piers are ana-lyzed.According to the mechanical characteristics and the typical disease analysis , several targeted reinforcement scheme is put forward ,which can provide references for the bridge of the same type.
