摘要
文章探讨了影响变截面连续箱梁桥悬臂施工抗倾覆稳定的结构设计参数以及组合工况,建立可靠性分析模型,采用规范推荐方法进行连续梁桥抗倾覆稳定的可靠性分析。根据国内外的规范现状,详细讨论了目标可靠指标的取值情况,研究结论可为类似工程施工管理提供参考。
In this paper,all kinds of structure design parameters and composite conditions which effect the anti-overturning stability of cantilever construction of continuous girder bridge are discussed in detail. Then a series of reliability analysis models are established. Using standardized methods,the reliability of anti-overturning stability of continuous girder bridge is analyzed. According to the present status of standards at home and abroad,target value of reliability index is discussed in detail. The research results could provide reference for construction management of similar projects.
