摘要
根据施工期预应力混凝土连续梁桥结构悬臂施工的特点 ,建立了悬臂施工中结构抗力和荷载效应的概率模型。应用结构动态可靠性分析原理 ,建立了桥梁结构悬臂施工期结构不同失效模式下的功能函数。本文以荆州长江公路大桥的三八洲连续梁桥为例 。
?Probability models of resistance and load effect of prestressed concrete structures during construction were proposed according to the characteristics of cantilever construction. Based on these models and time dependant reliability analysis principles, functions of two failure modes for analyzing the reliability of prestressed concrete structure during construction were developed. The method was proven to be feasible in the construction of Sanbazhou Continuous Bridge of Jingzhou Yangtze River Highway as an example.
