对桥梁上部结构整体抗倾覆稳定研究现状分析,剖析其计算力学原理及理论计算依据,并以一实桥为例,探讨独墩宽幅鱼腹式截面梁桥抗倾覆性能.借鉴最新规范研究成果及相关抗倾覆计算原理,引入抗倾覆稳定系数概念及其计算公式,对该桥进行整体鱼腹式箱梁的抗倾覆计算研究,同时与传统箱梁比较分析,所得二者抗倾覆稳定系数差别甚微,表明该类桥梁在抗倾覆稳定性方面并未有独特的优势.

On the analysis of anti-overturning capability present study over the whole upper structure of bridge, analyzing its computational mechanics principle and theoretical calculation basis and in the case of a real bridge, this paper is aimed to study the anti-overturning capability of a wide fish-bellied segment bridge with single pier. Based on the latest criterion theory and the anti-overturning calculation principle, introducing the stability coefficient and its calculation formula, this whole fish-bellied box is studied on the anti overturning calculation, meanwhile compared with the traditio...
