摘　　要：文章对独柱墩桥梁抗倾覆改造加固研究现状进行了分析,分析影响独柱墩桥梁抗倾覆稳定性的因素,针对性提出改变梁墩连接形式、变单支座为双支座、增加独柱墩双支座之间的间距、增加桥墩减少跨度、增设钢盖梁及对应支座等独柱墩桥梁抗倾覆改造加固技术。文章对提出的独柱墩桥梁抗倾覆改造加固技术进行了研究分析,强调了各改造加固技术需要特别注意的问题。The research status of anti-overturning reconstruction and reinforcement of single-column pier bridges is analyzed. This paper studies and analyzes the factors affecting the anti-overturning stability of single-pier bridges, and puts forward some anti-overturning reinforcement techniques for single-pier bridges, such as changing the connection form of beams and piers, changing the single support to double support, increasing the distance between single-pier and double supports, increasing the pier to reduce the span, adding steel cover beams and corresponding supports. In this paper, the anti-overturning reinforcement technology of single-column pier bridge is studied and analyzed, and the problems needing special attention for each reinforcement technology are emphasized.
