独柱墩式连续梁桥抗倾覆分析及加固治理设计

Analysis for Overturning Stability of the Beam Bridge Supported By Single- Column Pier and Reinforcement Design

为了减少独柱墩式连续梁桥倾覆事故时有发生的现状,以实际工程中典型的匝道桥为背景,通过对该类桥梁进行结构力学分析以及主梁倾覆稳定性分析,研究其结构倾覆的本质特征,并根据验算结果提出了相应的加固处理措施,可供新桥梁的设计以及已有桥梁加固治理设计提供参考。

In order to reduce the risk of the overturning of the beam bridge supported by single - column pier, The structural mechanics analysis and overturning stability of the beam is deduced in this paper, and the overturning stability is studied based on the typical ramp bridge of the practical engineering, provide references for the design of the new bridge and reinforeement design of the old bridge.
