独柱墩连续梁桥横向倾覆稳定性研究

Study on Lateral Overturning Stability of Continuous Beam Bridge with Single Column Pier

目前,关于独柱墩桥梁倾覆倒塌事故的报道屡见不鲜,论文以某独柱墩连续梁桥为工程背景,依据相关文件,采用有限元软件MIDAS CIVIL建立了独柱墩连续梁数值模型,分析了该桥最不利工况下的横向倾覆特性。

Given recent reports on the overturning and collapse accidents of single column pier bridges are still common,this article takes a single column pier continuous beam bridge as the engineering background,and based on relevant document,a large finite element software MIDAS CIVIL is used to establish a numerical model of the single column pier continuous beam,and the lateral overturning characteristics of the bridge under the most unfavorable working conditions are analyzed.It is expected that the results ofthis paper can provide a reference for the studyofoverturning stabilityof singlecolumn pierbridges.
