摘　　要：以一座三跨(80m+180m+80m)预应力混凝土斜拉桥为工程背景,利用有限元来模拟真实的桥梁施工过程,进行空间受力分析,得出在斜拉桥主梁施工过程中横梁预应力效应的分布规律。Taking a three-span（80m＋180m＋80m） pre-stressed concrete cable-stayed bridge for the engineering background,the regularity of distribution of beam pre-stress effect during the construction of cable-stayed bridge girder is obtained through conducting space force analysis by finite element simulating real bridge construction process.
