摘　　要：以灌南县人民桥为例,讨论了三跨预应力混凝土连续梁桥施工全过程仿真分析的建模依据及建模过程,并对结果进行分析,计算出理论预拱度,以指导该桥的施工线形控制。The construction process of a presstressed concrete continuous girder bridge, Renmin Bridge located in Guannan County, is simulated numerically in this paper. The modeling of the bridge structure is established and checked based on the finite element method, then the time varying responses are analyzed during every construction stage based on the data recorded from existed parts of the structure. The analysis results are used to control the constmction quality and safety of the bridge.

关 键 词：预应力混凝土连续梁桥 施工全过程仿真分析 理论预拱度
