摘　　要：0号块梁段是大跨度预应力混凝土连续梁桥设计及施工控制的难点和关键点之一。本文采用ANSYS软件和圣维南原理对某大跨度连续梁桥0号块梁段进行空间受力分析,获取了0号块的局部应力分布规律,其计算结果为该桥的设计提供了一定的依据,并为同类工程提供有益的参考。Segment No.0 is one of dittlcuities and key points for large - span pre- stressed concrete continuous beam bridge design and construction control. In this paper, ANSYS software and the Saint - Venant principle are used to analyze se^nent No.0 . The spatial analysis, access to segment No.0 of the local stress distribution, the calculated re- suits for the bridge is designed to provide a cmtain amount of basis, and to provide a useful reference for similar projects.
